Picking a hotel in St. Constantine and Helena comes down to how central the spa is to your stay. The three hotels are a large health resort with eleven mineral pools, a mid-sized hotel with its own spa centre and thermal access, and a smaller balneology hotel with mineral-water pools. All three hold Bulgaria's top official category.
Choosing a hotel in St. Constantine and Helena
Start with the spa, since it shapes the stay more than anything else in the resort. Ensana Aquahouse Health & Spa Hotel is a full health resort with 11 mineral pools, five saunas and a medical spa, which suits families and anyone planning a longer health stay. Astor Garden Hotel pairs its own spa centre with access to Aquahouse Thermal & Beach, which suits couples on a spa break. Balneo & Spa Hotel The Palace is the smallest of the three, built around a balneological centre and mineral-water pools, and it is the only one that lists accessible rooms.
For the beach, Astor Garden Hotel lists access to the Aquahouse thermal and beach complex and The Palace has a beach pizza bar, so ask each hotel how guests reach the sand. If you are travelling for work or a group event, ask about meeting space before you book.

Best hotels in St. Constantine and Helena
Ensana Aquahouse Health & Spa Hotel
Who it suits: families, and couples who want the spa to be the main event.
This is the largest hotel of the three, with 411 rooms, and its wellness offer is on a different scale from the other two. The Ensana hotel lists a wellness and spa area of 6,000 m² with 11 mineral pools, five saunas and a medical spa. For families there is a water slide, a kids club and a playground, and it is the only hotel of the three listed as family-friendly.
Worth knowing: a hotel this size suits guests who value facilities over intimacy. If you want a smaller base, look at the other two first. For medical spa programmes, ask how consultations and treatments are booked before you arrive.

Astor Garden Hotel
Who it suits: couples and friends who want a hotel spa and thermal access without staying in the biggest complex.
Astor Garden Hotel gives 230 rooms and runs its own Astor Garden SPA Centre, which publishes a spa menu. It also lists access to Aquahouse Thermal & Beach, so you can combine your hotel's own spa with thermal and beach facilities during the same stay.
Worth knowing: the hotel publishes fewer facility details than the other two. Before you book, ask what the thermal access includes, whether it applies every day of your stay, and which treatments you book separately. It is not adults-only, so expect some families around the hotel.

Balneo & Spa Hotel The Palace
Who it suits: guests who want balneotherapy, and travellers who need accessible rooms.
Part of the Sunny Day group, Balneo & Spa Hotel The Palace has 154 rooms, the fewest of the three. It lists a balneological centre, mineral-water pools and a separate SPA centre, plus a beach pizza bar for something casual. It is also the only hotel here that lists accessible rooms.
Worth knowing: ask whether balneology programmes begin with a consultation, and if so, allow time for it early in your stay. If you need step-free access or an adapted bathroom, confirm the exact room type before you book. The hotel is not adults-only.

Spa styles compared
- Health resort: a large spa with many pools and medical treatments under one roof. Ensana Aquahouse Health & Spa Hotel fits this style.
- Hotel spa plus thermal access: your own hotel spa, with access to a separate thermal and beach complex. Astor Garden Hotel fits this style.
- Balneology hotel: treatments built around mineral water in a smaller hotel. Balneo & Spa Hotel The Palace fits this style.
Balneology means treatments that use mineral water. If you only want to swim and relax, any of the three works. If you want a structured programme, focus on the two hotels with a medical spa or a balneological centre.
Which hotel suits you

Planning tips
- Ask what spa access comes with your room: which pools and saunas, at what hours, and which treatments you book separately.
- Check age rules for saunas and thermal pools before travelling with young children, since spa areas often set their own limits.
- Book popular treatments ahead, especially for weekend stays.
- Pack for both pool and beach, since Astor Garden Hotel lists thermal and beach access and Balneo & Spa Hotel The Palace has a beach pizza bar.
- Compare the board plans before you book, as each hotel takes a different approach.

Questions
Which hotel in St. Constantine and Helena has the most pools?
Ensana Aquahouse Health & Spa Hotel, by a wide margin. It lists 11 mineral pools, five saunas, a medical spa and a wellness and spa area of 6,000 m². The other two hotels list mineral-water pools or a spa centre but do not publish a pool count.
Which hotel is best for families in St. Constantine and Helena?
Ensana Aquahouse Health & Spa Hotel is the strongest fit. It is the only one of the three listed as family-friendly, and it lists a kids club, a playground and a water slide. Neither of the other two hotels is adults-only, so children are welcome, but they publish fewer family facilities.
Are there adults-only hotels in St. Constantine and Helena?
Not among these three. Ensana Aquahouse Health & Spa Hotel, Astor Garden Hotel and Balneo & Spa Hotel The Palace all state they are not adults-only. For a couples' spa break, Astor Garden Hotel, with its own spa centre and access to the Aquahouse thermal and beach complex, is a sensible place to start.
Which hotel offers medical spa treatments?
Two of the three. Ensana Aquahouse Health & Spa Hotel lists a medical spa, and Balneo & Spa Hotel The Palace has a balneological centre and mineral-water pools. Astor Garden Hotel lists its own spa centre, so ask it directly about medical treatments. For any medical programme, check whether a consultation is needed before you book.
Which hotel has accessible rooms?
Balneo & Spa Hotel The Palace is the one that lists accessible rooms. The other two hotels list no accessibility details, which does not mean they lack them. If you need step-free access or an adapted bathroom, confirm the exact room type with the hotel before booking.
Which board plans do these hotels offer?
The three hotels take different approaches: one publishes an all-inclusive plan, one half board, and one both bed and breakfast and half board. Choose by how often you want to eat out in the resort, and confirm the plan with your hotel before you book.
