Yiannis' place is amazing!
The space itself is very hip, well decorated, clean and comfy!
There were guests before us and we had arrived at around 10am and check in wasn't till 2pm so we found a place to eat literally just around the corner from the apartment and stayed there till 2pm
Once we got in, Yiannis' mum was just finishing up cleaning and was kind enough to show us on a map of Athens where the apartment was, where the Metro stations are and a nice scenic walk to the Acropolis. Yiannis also called at the right time and they both gave us recommendations on where to go, there's also a board in the kitchen which has recommendations of restaurants to try!
The bathroom is clean and works great! Although you have to hold the shower head as it's not attached to the wall but it was fine.
The location of the apartment is 10/10
We walked about 5-10 mins to Monastiraki Square everyday, and there you will find a Metro station. So it's very central and we loved it. There's also a little lane of restaurants which we found about a 5 min walk from the apartment and we had dinner there sometimes.
Overall I would definately stay at Yiannis' place again :)
