The apartment was more than enough and we had everything we needed. Gertsanik gave us clear infos that made our check in and check out very easy plus many recommendations and fast replys. The area seemed safe to me(at least compared to others in which i've been in Athens). It is extremely close to the metro and there are a lot of restaurants and stores around.
I enjoyed every single coffee on the balcony! :) (the view is quite pretty) I totally recommend it!
