I visited Fotis' place along with 5 friends( two of them couple) and we had a great time.
Communication was very fast and helpful.
Our arrival was late at night but that was no problem for Fotis to welcome us personally and give us two set of keys which was really helpful and we hadn't though about it.
The place was spotless in a great place very comfortable and with lot of amenities.
We had absolutely nothing to complain about, I strongly recommended it for either friends or families and if I am with a large group in Thessaloniki again it will be definitely top in my list.
