Sandra offers a very friendly welcome to this self-contained flat, and she understands English without a problem. The apartment is in the centre of Thessaloniki, 10-15 minutes walk from the White Tower, Aristotle Square, the Archaeological Museum and the Vellidio Convention Centre. You can view the Agia Sophia church from the balcony. There are plenty of shops and restaurants within 10 minutes' walk.
Warning: The rooms can get warm and stuffy. It took me a couple of days to decide whether I slept better with the noise of the air conditioning running, or with the window open and noise from the street. If you already live in a bustling city, then perhaps this is not a problem for you.
Another warning: the bathroom is very small. No problem for me, but large people may find it too uncomfortable.
