We stayed at Christos' apartment for 3 nights. We had a wonderful time.
Especially:
+ VERY clean, clearly someone paid a lot of attention to making sure everything is clean, fresh and new
+ Modern, well kept facilities (shower, toilet, bed, etc.)
+ Christos made an effort to help us checkin late and checkout late and communicated very well
+ Spacious apartment - with a large balcony, living room and bedroom. Excellent for 2 people
One point to be aware of is the location. It is just outside Naousa, on a main junction, just above a supermarket - which makes everything very convenient and close (including super close groceries!) - but it felt a little strange for us to live on top of a supermarket in the beginning. Not a residential area or nice to wonder around on foot...
