We spent 9 days in the apartment and they were very enjoyable. The position is perfect. Very close to the center and at 3 minutes from metro station. Shops and markets were easily available nearby the apartment. Located inside a courtyard, the apartment (2nd floor without lift) was very quite. The apartment equipment was complete and of good level.
For a 4 people group the situation is perfect. Probably the space would be a bit limited in the case of larger groups.
Finally the host and the staff was very professional and attentive.
We would certainly pay a second visit.
