We stayed at Evan's place for one night as we were transiting through Athens. The location is superb, one step out of the house and you're in the midst of Athens. Everything is within walking distance and that makes you feel like part of the city and its inhabitants.
The flat itself is nothing special even though the view from the balcony is awesome.
Communication with Evan was great, upon arrival we were also given a larger place than booked. Would come again! Definitely very good value for money.
