Naya's place is perfect for a short stay in Thessaloniki. Located just above Platia Aristotelous pretty much everything is just a short walk away. Busses to and from the airport stop close by so also no need to use Taxis or else. The apartment itself is spacious and beautifully decorated. We fell in love with it right away! The check-in is very easy with keyboxes to make it very flexibel. Naya provides a wide range of guide books etc for Thessaloniki which is really helpful. Just be aware if you are very sensitive to noise - the Agiou Dimitriou Church is right next to the apartment and rings you early in the morning. This was not a problem for us as we love to get up early and the overall experience of staying where the locals live. You can also find many bars, small stores and cafés around to provide you with everything you need.
Overall we loved our stay and definately recommend it to everyone coming to Thessaloniki for a short get away and experience the city from its various parts.
