This is a beautiful and cute apartment. Looks exactly like on the pictures, is very clean, nicely decorated, has all the amenities you need. Great wifi, well equipped kitchen including all basic supplies. There are two cute balconies with great views. It is warm in the winter. I travel to Athens 3-4 times a year now for many years now and this is probably the best I have had at this price pointy. The hosts are very helpful, provided loads of local tips and suggestions, very good communication and flexibility.
As far as the location is concerned it is good for Athens - very near to the lovely Psiri area, the Acropolis, Monastiraki and Ermou street. In the direct vicinity there are a few very nice restaurants and cafes, two or three theatres, a little park and an art gallery. It has to be noted, however, that the area is a bit rough in places with many run down buildings, addicts, homeless and a little red light district not far. Maybe not the best for kids or sole female travellers.
