We had a great stay in Athens! We were 3 people so everybody had its own room. The appartment is amazingly spacious considering the location, which is great. We walked everywhere.
The only downside is the noise you can hear from the busy street in all of the rooms. Additionally there was a construction going on in the appartment next door, which is of course temporary and not our hosts fault.
Check in and check out were really easy and our hosts gave us the feeling of being home - really lovely to talk to. Thanks a lot! :)
