Bessie's apartment is in the perfect location: it's central, close to the metro station that you'll take to go to the airport (150 m) and in the lovely area of Monastiraki. You can walk to every point of interest in minutes.
The house is very very clean and spacious, it has a fridge, a freezer, a boiler, a washing machine and in the shower you'll find a selection of shampoos and body detergents and clean perfumed towels.
Bessie is the best. She always answers the WhatsApp messages in minutes and she's always kind and caring.
