The arrival and departure were done without any problem and the hosts gave us all the facilities. They also attended promptly and very kindly to all our questions. From Sintagma square, you are very easy to reach the apartment.
The apartment is confortable and in accordance with the description given by the hostess. The main room has natural light overlooking a narrow, quiet street with no traffic.
The kitchen has everything you need to cook simple dishes.
It is a renovated flat, and the furniture is also new. The heating (by air) was enough, despite suffering a "cold wave" with much lower temperatures than normal.
The location is excellent, and you can walk to the main sights. If you want to use public transport, Syntagma Square is a step away, and there you will find all kinds of transport to reach any part of the city, or to go to the airport or the port of Piraeus.
In short, a cozy apartment and very well valued.
