I booked this place for my mom so stay 3 nights. The first thing is that the location is incredible. Koukaki is lovely, walking distance to the acropolis, it's really great. It's on a tucked away street so you don't get street traffic. I think from the photos it looks brighter than it is. I knew it was a basement, but it was rather dark and damp. Unfortunately there were issues with the toilet, which the neighbours upstairs had as well, and my mom got bit by a bedbug the first night, so we asked to leave early. Luckily the host was very fast and respectful in acting, they refunded the 2 nights and told us they hadn't had these issues before, so I would trust that they would take care of it quickly. As other folks have said, it is certainly good value for the location, but it's more a place to sleep, not to spend much time in.
