We had a 3 person apartment and it was nice and comfortable but the bathroom (1 bathroom) - although it was very clean - was tiny ! And also it didn't have any windows, just a fan for ventilation, so it was hard to get fresh air in there.
Cleaning lady comes everyday and she changes the sheets and towels once every 2 days (that's the rule). But she forgot to change our towels once, and another time she took the dirty sheets from the couch I was sleeping on (I was the child in this story) and forgot to leave clean ones.
Still, we called Nancy and she took care of the problem in no time!
Very nice design, just renovated in the winter '13-'14, pretty furniture.
Very close to the beach (2 minutes walk). A 6-7 minutes walk to the more lively part of the beach, with many bars, cafes and restaurants.
Great prices (we paid 285€ for a 5 nights stay - 3 people - without breakfast - end of June).
The host - Nancy - is very friendly and helpful, and you can ask her for beach recommendations and advice about what activities you can do on Sithonia anytime.
Also, the area is very beautiful, there are some wonderful beaches and places nearby - like Orange beach, Goa beach bar, Toroni beach etc. We recommend to go there by car or rent one, so you can move around and explore the place. Sithonia is a quite small peninsula, you can go around it by car in 90 to 120 minutes, so make sure you go every day to a different beach, it's worth it!
