I just stayed one night at Effi's place, but I wish it would been more !
The flat is very beautiful and well decorated, with simplicity and very good taste. The neighbourhood where the flat is located is lovely, it is a square with a church, trees and kids playing, full of café and restaurants, very near to the metro station on the top of it.
Effi is a great person, very warm, welcoming, and available for any questions you have. I really enjoyed speaking with her...
I absolutely recommend !
