Κώστας was very friendly. He was quick and patient to respond to my queries about his place and getting around Athens. I stayed here for 3 nights during the summer. The room can get pretty warm but it's cooler at night. If you are used to living in comfort, this might not be the place for you unless on a tight budget. Do keep in mind that you pay for what you get. It's not very clean (pretty dusty) but it is in a livable condition. It is in a pretty good location for the price - it's about a 25 minute walk from this place to Acropolis, Ancient Agora, Roman Agora, Hadrian's Library. Syntagama is also walkable (around 27 minutes). There are bus stops and the Metro station nearby (about 5-10 minutes walk). All in all, I had a decent stay and would recommend this place to solo travellers on a tight budget.
