This location is the best! It’s in the middle of Athens with no traffic noise! There’s a gentle murmur from the people in the restaurants on the street below, but it’s at a level that as a light sleeper totally didn’t bother me. It’s also literally 3 minutes walk from Monastiraki square and metro, which runs a direct line to/from the airport for 9 euros one way. It was super easy to find which is also a bonus.
The essentials I want in accomodation are temperature control, a really comfy bed, and a hot shower with great pressure. This place has it all. The host was really prompt at responding to our messages, too. Would definitely stay again and recommend.
