Costas's place is everything you need for your Athens experience. Exarcheia is the youngest and most vibrant neighbourhood in centre Athens and in general the location can't be better, close to the very centre and in a walking distance to any area that you would like to explore.
The flat is very nicely decorated with a vintage vibe and all the conforts. The bed is one of the best we have ever found in an Air BnB, which is highly appreciated.
Check in and out were very easy and smooth and Costas was very friendly. Perfect stay!
