I am looking for a good cheap hostel/pension (40 to 50 euros for a double). My girlfriend and I will be in Athens from 17 May to 20 May. I am arriving one day earlier. I was going to stay at Pella Inn in Monastiraki because it is centrally located, close to the Metro, has dorm room (for my first night) and inexpensive doubles. BIt it got such bad reviews on Trip Advisor. Does anyone have any suggestions for a place that has a similar location and price but is better? The guide books are completely unhelpful on this question.
