All was nice - you can reach by foot a lot of interesting places, there are enough cafes, restaurants, a shop, at a couple of minutes walk.
Things you should consider: if the living room is used for sleep, the person(s) sleeping there should be used with the street noise in the night (I am not and I had to sleep one night there, I wasn't very happy). Turn on hot water some time in advance, I did not take note of that and had to wait. The elevator is very small - I barely entered after the stroller went in, lucky that the stroller wasn't a big one. On the other hand, reaching the second floor is faster without the elevator.
When I will be back in Athens, I will consider this place again, without the stroller this time.
