We visited Angelos' house for a special occasion and the house was perfect. At a great and very central location, close to bus stations, supermarkets and everything you might need.
The house itself was wonderful, very cozy, colourful with all utilities needed. Warm enough even for the coldest of days. WiFi was good and there was even Netflix available.
Communication with Angelos was good and quick when needed, and check-in/check-out was just as easy.
Definitely recommending the house and will certainly stay again when visiting Thessaloniki.
