Yannis is a lovely host and gave some good suggestions about what to do in Athens on arrival.
The appartment is very nice and clean. It is a 2minute walk from a supermarket, restaurants and a metro stop, which you can take for 4mins to get the centre of the city.
However, the garden is shared with an upstairs neighbour, who does not like any noise in the garden at any time and is very rude. This meant we could not use the garden, one of the best features of the appartment without getting shouted at.
A part from this, it is a lovely appartment, in a great location and Yannis is a very good host.
