The apartment is located in nice neighborhood, with a lot of things to discover all around. We spent 4 wonderful days in this location and never used a taxi or other public transport - all sightseeings can be reached on foot. The district is lively during the day, but not noisy, and at night it isn’t loud.
You can find everything you need, kitchen is small but well-equipped with all necessities, bathroom has got a hairdryer and a washing-machine and many other stuff you may need during a stay. Main space is thoughtfully decorated, it looks like there are a lot of objects in a small room, but it’s still comfortable and enough spacious for 2 adults. The design is excellent, very warm and cozy.
The host is nice and friendly, gave us some recommendations about the city and was always in touch.
I needed good stable Wi-Fi connection and I had it, the speed was about 20-25 mbps download and 5-6 mbps upload, I could easily make several important video-calls.
However, the cleaning was not 5 stars, but it was ok. I would give it 4,5 stars - some plates had leftovers on them and kitchen tables were in crumbs a little, but we could manage this problem ourselves easily :)
To sum up, if I need to stay somewhere in Thessaloniki again, I will choose this apartment with no doubts.
