We really enjoyed our stay at Dreamin Athens. The location is perfect with a great view of the Acropolis and the apartment was exactly as we expected. It is also in a very central location for the restaurants and sites. The hosts were very responsive to all our questions - we can't really fault them or the apartment.
There was building work outside the apartment which we hadn't been warned about so it was a bit noisy in the morning. A couple of little things to improve the apartment would be if the shower was attached to the wall and a plug for the bath. I would say these are tiny complaints as we would definitely stay there again and recommend it.
