The staying was perfect! Location is really in the center and everything is close 2-10 min walk. The apartment itself is like on the pictures, very cosy and clean, decorated with retro-style details. The host provides you with all you need and even more. I arrived after midnight because of late flight and George met me in the apartment and explained everything. Also they let me to check out late as well cause my flight back was very early in the morning and they kept my luggage in a safe place so I can have time in the city before leaving to airport. The one and only drawback was WiFi. It didn't work properly all the time I've been there. I tried rebooting it couple of times and it helped for some time but then again came back to issues. I bought a local SIM card and I had internet connection but it was limited so WiFi would be very helpful. Fair to say that I didn't tell the host about the problem. Maybe they could do something more than me but my stay was short and the sim card worked well so I decided not to bother.
Anyway the host is great and apartment is a perfect stay. Highly recommend Ioannis and this place! Thank you very much!
