Its great apartment in central Athens, there is big park nearby to walk with children and street market twice a week with fresh and tasty food. The apartment is very comfortable to stay for night or day when its hot outside. It has 2 bedrooms and guestroom where you can eat with family or rest on a couch with nice TV(it has HDMI input), children will find some space for playing games too. All three rooms have air conditioning which is very convenient. I had to do some work so was happy to find good quality internet access and coffee machine. :) There are wide avenue close to the building with bus stops, so it was easy to get to any part of the city, but if you are traveling with infant, baby may have hard times getting to sleep because of noise from road even in the night. It was also nice walking to the center of the city or subway station(takes 20 minutes walk through park). Kitchen is pretty big and has everything we needed to prepare foods for us. Everything else is as described or better and photos are real :) Also host was very kind and allowed us to stay couple hours more to finish preparations for travel and flexible check out time is something you should not underestimate when traveling with family.
In conclusion we are thankful to Elena and Manolis, we had a great time!
Thank you!
