We stayed at Tomas and Cristina's house for 2 days.
The place was tidy, clean and very elegant. The sheets and towels were clean and fresh. In the kitchen there were coffee capsules and 2 big bottles of water.
It's very close to the center and all the local cafeterias and restaurants.
I highly recommend it, you won't regret your choice. We will definitely book it if we come in Thessaloniki again.
