Our stay at the Nicozy house was overall very pleasant. The flat was very cozy and had everything one would need for a week stay in Athens. The location is a 10min walk to 2 metro stations and a 25min walk to the city center. There are many cool bars and restaurants in the area.
Unfortunately I have to take one star off due to a problem in the bathroom: the water in the bath tub did not drain at all. You ended up in a quarter full bath after not even a minute of showering.
We contacted Νικολέττα a day after our arrival, telling her about the issue, which she must have known about, since the bathroom had to be cleaned after previous visitors. The response was quite fast, but there was no solution to the problem, because a potential fix required the flat empty.. I believe and hope this will get fixed soon, so that no other guests have to deal with this unnecessary issue. :)
