We had a very pleasant stay in Athens and as budget travellers Enely's place was perfect for us. Enely was also really flexible with the check in and also provided us with good instructions on how to get to the apartment. The apartment is as described and has every necessary thing you need. Everything worth seeing was in walking distance, no public transport needed. There are also plenty of cafes, a small supermarket and affordable food places nearby.
If you are a light sleeper then ear plugs might be a good idea as there is a bar right next to the apartment, but this wasn't a problem for us. And final note: the building has a very nice doorman!
