Our stay in the apartment of Alex was very pleasant. A cozy, very well decorated apartment with enough comfort. It was also clean. On the one hand all the important sights were at walking distance, on the other hand it was quiet and still. The subway was close, so we could travel to/from the airport with the metro. The biggest plus for us was the bed and soft pillows.
Alex is a nice host. He gives clear information (with pictures). He answers quickly, and kindly, on questions. Highly recommended!
