The location is perfect: very close to the center but also not too close, so it was quiet. The neighbor hood is safe and clean.
There are small cafes around this apartment, which was nice, and I recommend Cafe Mare if you are looking for nice cafes to have breakfast/lunch/dinner/drinks with a nice view :).
Facilities are well organized-you will find most the things you need-wasserkocher(sorry cannot think of this English term ;)), air conditioning system, hair dryer and etc. Sometimes wifi was bit slow but it was okay.
Rooms were clean and cozy.
I definitely recommend Agelos’s apartment :)
