The spa hotel is a conveniently located place with a cozy ambiance. The staff is helpful. The spa is small but OK for a refreshing dip into the pool in the afternoon. We had a room on the 4th floor, which turned quite hot during the day. Though the weather was very hot at that time, it cooled down during the night, so it was quite OK for us. Still, we later found out that the hotel offers air-conditioned rooms on the 5th floor for the same price. So make sure to get a room on the top floor. The breakfast offers a variety of different kinds of food. Especially the availability of traditional Czech sausages was the highlight for us. Make sure to reserve a parking lot for your stay. The hotel offers a limited number of parking lots in front of the house. As parking in general is very complicated in this town, you might end up using one of the carparks at the outskirts, if you don't reserve a place. Book your places in advance!

I really enjoyed staying in this hotel “Iris” in Karlovy Vary. Head Doctor Mr. Yuriy Onisko attentive, head nurse Mrs. Tana (apologies if spelling is incorrect, and I can’t remember the surname) organized SPA treatments well and does the CO2 injections so well, SPA staff is professional, kitchen staff makes selection of foods, waiters are nice, cleanliness is very good! Reception staff is quick and helpful. Thanks to all responsible staff of “Iris” Hotel. It is Quiet Hotel, although full of people, even with kids, quiet, not big Hotel. I used to stay in 5 star hotels in Karlovy Vary in the past, but somehow such 4* hotels also good. I wish to return back in this hotel when I can next time.

Small boutique hotel (30 rooms or so). Its success is due to excellent Ukrainian doctor and very modern spa and medical facilities - all in mint condition. Excellent and various food - also due to UA chef. Nice small club for evening conversations or TV However some glitches should be expected when staff tries to deal with unexpected - then they fail, but if you are OK with very high general level of service, than its probably one of the best small hotels in the town. Highly recommended (again, despite some failures, which should have been treated in a more professional way, but that the way of the Czech service, which is usually much farther from perfect than in Iris) Beware problems with elevator
