However the neighborhood, the streets and also the block of flats outside seemed a little bit old/ugly and not too friendly - the flat inside was amazing and really clear. It's ideal for 2 or 3 person as well. The little kitchen, bathroom was really clear too and the whole flat was really cosy. So who cares how does it look like from outside? :-)
The location of the flat was really nice too because it was really close basically to all of the main attractions. Even the subway and the tram was quite close so it was easy to get to the heart of the city or to the different beaches as well. We walked a lot but we recommend to have a daily/weekly season ticket as well so you can use the public transportation too.
Highly recommended for couples, singles or other friends! :-) Athens was just amazing!
