We returned from Bulgaria 7 Aug this year and i guess we visited the same doctor as you had twice, he was nice and helpful, my man was ill by food we think. We have only good things to say about the hotel, pool, dr, and staff.
We will return next year.

We stayed last year and had such a good time. We are going back again in june. Reception staff were brilliant, hope they are still there.

I've lived in Sunny Beach for a one week and I must say that Mercury hotel made a most favourable impression on me. This is not cheap hotel, I admit, but it's worthy to be visited. Service was irreplaceable. Very polite and well brought up young people.
Except immaculately clean swimming pool and many drinks to choice at the bar, there is also a restaurant with friendly atmosphere and qualified waiters.
I recommend Mercury hotel to all of You, who care about high standard of living and comfort connected with safety.

lovely hotel, the rooms are spacious and well decorated, food, pool infact everything was great.
cann't wait to go again!!!!!

I have just returned from Sunny Beach and did not stay at Hotel Mercury but across the road. We went to Hotel Mercury every night to their own bar which was fantastic. The staff are the best in Sunny Beach and really made our holiday an enjoyable one. We made really good friends with them and are booking with them to stay here next year. 10/10
