Panos is a fantastic host, very nice and was flexible for check in and check out. He always replied immediately. We really enjoyed the stay, thanks again.
The place is great, very clean and spacious. (+hot running water nonstop -AC only in the living room, however there is a ventilator in the bed room). It is in a quiet neighborhood, and for a drink there is just around the corner a nice little bar. Attiki with the Green and red Metro line is about 10min walk which takes you to the Center (Monastiraki) in just a few minutes. At night the taxi is around 10€ back if you are somewhere around Monastiraki/Psiri.
The apartment is a really good place to explore Athens and its night life, and we can fully recommend it.
