The place is lovely and Sylvia and Daniela are warm and friendly. They have an awesome location that is very near everything, shops and the market are a short walk away. I waked to everything and felt totally safe. Athens is an amazing city and this place truly lets you experience the best of it.
A few tips for people coming from the airport, you must switch metro trains to get off at the right stop. Its simple enough to do but if you forget like me and get off on the wrong stop, do not trust the air B and B app for directions, the address that it sends you to is 8 miles outside of city. If you are not stupid like me you should be able to avoid this no problem lol ;) enjoy the city.
