Very nice place. Clean and well maintained. Air-conditioned and with plenty of hot water. Very spatious balcony. Very close to the St. Demetrius Church. Easy access to the building.
There are only three cons: Extremely small bathroom. Actually, it is the smallest bathroom I have ever seen.
The internet is very slow.
And if you come with a car, just forget it. There is a private parking lot (about 300 methers), which will cost you 15 euro per day, and you have to leave the car key there. Extremely uncomfortable for arrangement and very annoying experience.
In short, the apartment is small but nice, though.
