We had a very nice stay at Fragiskos' place. We confirm that the flat has been fully renovated and is very comfortable. It is a spacious flat with big bedrooms, living room, large entrance and decorated harmoniously. It is also very quiet with double-gazed windows. It can accommodate easily a family, and there are nice equipment for babies too. The balcony on the first floor enabled us to enjoy the sunset and have a glimpse to the neighbourhood life. There is a bakery at the end of the street. Taxis are also very cheap (around 4 euros to reach Syngtama square) so if you are with kids, we really recommend this flat. Aircon and Internet are available too and working :)
Fragiskos is a super host and was always available for us (he lives on the second floor). He spoiled us with a lot of nice thoughts (from the kitchen to the bathroom).
By the way, we loved the bathroom and we slept tight thanks to the comfy beds. Linen were spotless.
Thanks again Fragiskos for sharing your place with us and giving us good advice to explore Athens.
