You could not ask for a better location. Sandra's mini-studio is right in the heart of the city center. Most of the major attractions are within a 10 to 15 minute walk and the studio is about one block from public transportation. A definite highlight is the balcony, which offers great views of the city, particularly Hagia Sofia. Great place to relax with coffee or a glass of wine. There are also countless restaurants and bars in the area, so you really can't go wrong staying here for a short trip.
I was a little concerned because the studio is a large (well furnished and equipped) room within a bigger apartment. It has its own bathroom, kitchen area, and the aforementioned balcony, so you have privacy. But being the night owl that I am, I was worried that I might make too much noise and disturb Sandra and her family when I came back late at night. However, this did not seem to be a problem, so no worries.
The apartment was super comfortable and I got a good night's sleep.The bathroom comes will equipped with extra things like cotton swabs and hair gel (BIG, pleasant surprise), so Sandra clearly puts a lot of thought into making sure her guests have everything they need.
Sandra was also super fast in responding to my many questions. I had an issue with the wi-fi on the first night. I messaged her the next morning and the problem was solved in less than an hour. She also provided me with some great tips on things to do and restaurants to visit. So like I said, you can't go wrong staying here. I plan on coming back to Thessaloniki soon and will definitely stay with Sandra again.
