We spent 10 day in Athens, in Helen's house.
It's a very clean, stylish place in a quite neighborhood.
I liked bed linens and blankets very much.
There were a lot of printed information about how to reach some points of interests.
Check-in/out processes and communication is excellent.
There were a printed article about the neighborhood and a street "something Negri " in particular. We liked that street and small cafes located there.
The neighborhood is great. Much better than the center of Athens.
We enjoyed local street market on Saturday, it was real fun, and good experience.
We had a problem with internet, though. It's an ADSL line with max 1mb. Helen and her son very kindly tried to solve that for us, but I don't think they were able. It's something with their ISP.
Also take note (it was a surprise for us), that however Bus stop is really close, and convenient, still the time between buses can be half hour easily. It's fine if you are planing go to the center once a day, but could be a problem otherwise.
