This place is perfect for exploring Athens, not to mention it's very comfortable, stylish, and clean. It's located on a quiet street only minutes walk away from the main attractions in town, and is very near the Monastiraki metro station. I was able to explore the city by foot and even comeback in the middle of the day for a quick nap.
There was indeed manufacturing related noise in the morning as mentioned by the host, but I find it fairly manageable. The place was quite at night and I had no trouble sleeping at all.
Anna and Maria are excellent at communicating and making sure I'm doing well. Their tips on public transportation was a huge help when my ferry arrived late and I wasn't sure if I'd be able to catch the last metro or not. I ended up arriving at the place without any troubles. In short, I had a really good experience staying here.
