Asteris is a great host. He helped us with the parking (very important if you travel by car), he came immediately to solve any issue we had (a small inconvenience at some point) and also made great recommendation for family restaurants and events taking place in Thessaloniki or places to walk with the kids. He is very correct, polite and helpful.
The place is clean , the bathroom is a bit small (if you go with kids :) , the kitchen is well equipped.
The place is central, close to the see front and shopping avenues.
I like very much Greece and this trip has reminded me of the good food and hospitality of Greek people. I wish you a very nice experience as well.
