Orestis was wonderful and super helpful and accommodating. The place was amazing and the location is pretty good. The noise from the clock towers did not bother us very much (at all?) after the first night.
HOWEVER, on Friday and Saturday night there is an extremely loud bar/bar district very close by. The loud music, amplified voices (think MC or karaoke) and those of the revelers, and overall volume level remained high until 4am both nights. It wasn't a deal breaker for us, but I feel it should be mentioned.
We rarely saw any open businesses during the morning, day or evenings for the immediate few blocks surrounding the apartment. A mere few blocks away and you are in the heart of anything you want in downtown Athens!
There was a problem with mosquitos overnight in the apartment. When we left the windows open to enjoy the sounds of the city and the wonderful Mediterranean breeze we were assaulted by the mosquitos. Roughly 40 bites the 1st night and 20 on the 2nd night. We stopped leaving the windows open and lost the wonderful breeze, but the mosquito issue subsided significantly. I might not have noticed them occasionally buzzing my ears in my sleep if it were not for the 1st two nights.
Orestis mentioned on check-in that there had been a recent comment on mosquitoes and I have told him about this. Given how helpful he was, I can't imagine that this will not be addressed immediately. But I would keep an eye out in the comments to see that it has been rectified.
Even with the mosquito issue, I would highly recommend this place. Especially if you're a night owl or not planning on being there Friday or Saturday nights.
