Top apartment !
Localisation is just perfect, many restaurants, bars at less than 5 minutes by walk. It's the same thing for the big monuments or cultural activities, the most famous are around 10 minutes, 15 maximum!
About the apartment, it was perfectly what me and my friends needed. A big place, everyone had his own good bed and we all have enough space to not walk on the each others.
And the last but not the least, Nicos is the best host that I've met. He his really nice and friendly and if you need advise or something else he will be there for you !
So don't hesitate, take this apartment!
