I stayed at Nadia for 3 nights. She is very nice and was very helpful during my stay at her home. I felt like at home. The day I arrived I was received by her daughter and met Nadia the next day. The guests' place is in the second floor with 2 rooms, a kitchen and a bathroom. I've got a spacious room. The room, kitchen and bathroom were very clean. At the time another guest was in the other room although I never met her.
The house is in a very beautiful and safe neighbourhood, 5 or more minutes walk from train station Sloterdijk, close to Amsterdam Central Station and 20 minutes ride to Schiphol Airport.
Nadia, her daughter and mother (who I met one day when she was visiting) are very nice ladies.
I fully recommend staying at Nadia. And if I go back to Amsterdam one day I would like to stay at her home.
