The worst experience I have ever had. I am not sure that it is a hotel at all, may be hostel is the right description.
Please never do that ......

Me and my boyfriend (my husband now) went there for Easter - to spend some time together away of the work. The hotel is located next to the railway station so was great for us as we came by train. The price for Easter was cheap and that was one of the reasons to stay here. The hotel is new and clean. The room is basic - nothing special. The breakfast was good - as it was Easter we had eggs and sweet bread every morning. There is also something like bar-restaurant in the same place where we had our breakfast. We had a small problem - my boyfriend left his magazine at the bathroom and after we came back we saw that it was missing - we called the reception and they said that the cleaning lady thought that is trash! Horrible! Was an expensive English magazine - as my husband had difficulties to read Bulgarian we found this expensive magazine for him and they decided to throw it out!

A warning!!! My VISA card was copied at this hotel and massive cash withdrawals was done about 40 days after my visit.

A general advice in Bulgaria is to never use a credit card for anything else than cash withdrawals in ATMs in monitored places, preferably in connection with banks... And do check the ATMs for possible scimming equipment.

Else the hotel was pretty dull and plain. The staff at the breakfast room was terrible. Constantly watching you like they check how much you eat or what you take...

Stayed at the Aqua Hotel in August 2006 for summer getaway. I expected a nice, clean hotel and it was met. But there were some bad things too. First the good:
1. The first night we were upgraded to a suite due to overbooking. It was very nice. Huge, clean bathroom. Huge room. Huge comfortable bed.
2. The rest of our my stay, I was in a standard double room. It was ok. Nothing special but clean. That's what I care about the most.
3. It's very close to the train station so if you are traveling by train then it is very convient.
4. Staff was good and nice overall.
5. Breakfeast was ok but don't expect much. It is Bulgarian breakfeast style which I didn't like too much while my stay in Bulgaria.
6. It is about a 10 minute walking distance to the city center and a 20 minute walk to the beach. So if you want to be closer than you should find something closer.

The bad:
1. Staff didn't have great English but it was ok. I expect that when I go to another country. There was one older lady that was not so nice and I avoided her as much as I could. I asked for a close internet cafe and they couldn't tell me where one is located. I found one on my own.
2. The shower ceiling in the standard room had some spots (maybe mold?).

Overall I liked my stay. I would return again. Great value for what you pay.
