We needed a late check-in and it wasn't a problem. There were detailed instructions, and Ioanna was available to answer all the questions we had despite the late hours. Before our arrival I asked for nearby park options and was provided with detailed information.
Then there is the cleanliness: it was sparkling clean. The AirBNB places are usually clean, but this was a level above everything I've visited! And the furniture is new and well maintained. The location is great. It is in the city centre, but is not noisy.
For sure we'll consider this apartment next time we visit Thesaloniki!
