Pangiota's apartment is about 1 mile from the White Tower. Just a brisk 15 minute walk along the promenade into the centre of the city.
The exterior of the apartment block looks a bit shabby, and it's not located in the prettiest area of the city, but don't let that fool you... INSIDE the apartment was spotlessly clean. It's very well furnished with all mod-cons (air conditioning, smart TV, good Wifi, big refrigerator etc.).
We had excellent communication with Panagiota in the run up to our arrival.. On the day, we were given detailed instructions about how to find the apartment, how to retrieve the keys etc. This was a painless process.
Part of the fun in Thessaloniki is being in the "thick of it" - yes the big tourist attractions are in the city centre (as are the £££ expensive restaurants) - but if you walk around some of the smaller neighbourhoods you'll discover some real gems.
We love Thessaloniki, and we'll be back at some point.
