Me and my sister stayed in Athens for five days. We booked this place few days before and the host immediately accepted our request. He couldn't be there for the check-in but he gave us really accurate indications to take our keys and to enter the place.
The room is very large and comfortable. The bathroom is to share, it's small but practical and cleaned by a cleaning service. The centre of Athens is 10/15 minutes by feet and it's near to all the most important attractions of the city and nearest to the night neighborhoods (Psyri, Plaka, Monastiraki) where you can have dinner or take a drink.
The host was very kind to share with us a list of bars and restaurants divided by meal. We tried almost all of them and they were all good and cheap.
At the beginning, we were a little afraid to come back home really late because in front of the house there was a big square a little bit dark and not crowded, but our host was really gentle to reassure us that is a really safe place. We tested it and he was right!
I really recommend SleepEasy in groups, couples, but also alone.
Big, handy and provided place. I'd surely come back :)
