We had an excellent stay for 6 nights. This is an absolute 5* experience.
The apartment is wonderful, very spacious, well decorated, clean and comfortable. The large balcony is an extra bonus. The apartment is well equipped.
Our flight landed late at night and Oleg met us in person to check in and also shared many tips. They were also flexible for our check-out.
The location is a 5 minute walk from Victoria subway station, which is 2 stops from Monastiraki where most of the things to see are. The neighborhood also has several supermarkets, bakeries, minimarkets... within a short walking distance from the apartment.
Highly recommended, one of my best Airbnb experiences so far.
