Sandy's place is an amazing place! (The owners are very friendly) She is a great host and there for anything you may need and will recommend you places to go.
The apartment is close to everything literally everything is walking distance. Shops, bakeries, restaurants and coffee shops and all other tourist attractions.
It is an easy access place.
The apartment is clean tidy with anything you may need it is fully equipped and a nice and very modern place! It is definitely one of the best places we have stayed and will be defintley staying here again when we come again to Thessaloniki.
