I had a marvellous holiday with my family. All hotel employees were friendly and only difficulty was having waiters with no English knowledge. I handled it knowing a bit of Bulgarian but might not be so comfortable with everyone
Good hotel with great spa amenities. Very good buffet style dinner, however breakfast was not well organized. Luck of plates in some areas, cold food ( fried eggs particularly)
Regarding overall design.:
Bathroom tiles are rough and dark and it makes not easy to maintain, craftsman of bathroom tiles also poor, is not matching to 5 stars hotel for sure. Also color coordination and room design are odd. Smoking in lobby bar is permitted, so for non smoking persons as us, not very pleasant experience.
