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.

We stayed at the Aqua hotel in the centre of Varna, and thought it was very comfortable. Our room did not have a double bed, but we pushed the two singles together and it was fine.
On our first night there we went to a little bar/restaurant next door to the hotel, called Vicki Tavern where we met Vladimir, the owner. He was so friendly, we have become good frinds since then, and still keep in touch. The food is lovely and the drink is plentiful. Everyone welcomed us, even though hardly anyone could speak English, I would definitley recommend it.
