Me and two friends stayed at Fani's apartment for two nights. It's in one of the best locations you can find in Thessaloniki, right by the Main Street, a 2 minute walk to the central square or the coast and right across one of the most delicious food spots in the city. The apartment was very clean and fully equipped, the beds were very comfortable. (It really has one double and two single beds - not one of those apartments saying it can host 4 people but has in fact one bed and two uncomfortable sofas - it can really make 4 people comfortable.) Even we never met Fani, we communicated before, during and after our stay and she was really helpful with everything, responding immediately. I'd definitely choose to stay here again if I ever come back to Thessaloniki.
