Some negative and some positive aspects. The former are related to the cleanness: the mattress was in an embarrassing state, full of dust and hair of previous hosts. The mini bathtub was completely ruined, it needs absolutely to be changed.
The building of the apartment is located among several buildings that completely cover the sunlight, so if you want to see how the weather is you have to go out and take some steps outside.
The host was ten minutes late at the appointment and, after giving us the key, he went immediately away. We have some problem of communication, since he answered me only after two weeks, three messages and after I contacted Airbnb assistance.
Positive aspects regard the position of the apartment, five minutes walking to syntagma place and ten/fifteen minutes walking to other attractions. There were all the other things written in the announcement.
