Stayed in an Executive Apartment for 6 nights, which was spacious, clean, comfortable and well serviced. The staff we dealt with were friendly and helpful, as was the taxi driver who met us and returned us to the airport. The additional cost over and above street taxis is worthwhile. We had breakfast each day which again was served by very pleasant staff and there are 4 set choices, English, Greek, French and American, which have to be pre-chosen the day before. Given a choice, we would not have selected every component of these set breakfasts and would have preferred to simply decide what we actually wanted to eat. However the quality of the food served was acceptable, if not outstanding.
Urban Nest is located in an interesting part of Athens and the surrounding narrow streets are full of bars and restaurants, with many places currently in the process of being redeveloped. So there is a good choice of restaurants and we particularly enjoyed Bandero. However as our room looked out on to the street in front of the hotel, where late night parties take place most nights, it was not the restful place we would have preferred after spending days enjoying the many wonderful sights of Athens. Unless you can sleep like the dead, I would therefore any visitors to Urban Nest to choose a room which does not have a street outlook.
