I had a good time at Virginias home. She is a really nice host, asked me several times If I need anything and offered me to use her kitchen and everything in it. She even allowed me to leave my bag at her place on the day of departure and to pick it up in the evening, before I left Amsterdam.
The flat is in a quiet neighbourhood, not too many cars, no tourists. Nevertheless it takes just 10 min by bike or bus to central station.
The flat itself is a bit bad soundproofed (I heard someone snoring ;) ), but still acceptable. The room is okay, nothing special, a bit more decoration would be nice - but if you are just there for sleeping, that's fine. Although the floors were freshly cleaned, I wouldn't recommend this accomodation to people who are obsessed with cleanliness. It wasn't dirty, but just not that clean as one could expect (Virginia told me, her cleaning lady didn't show up that day, so maybe that's why).
Conclusion: very nice and uncomplicated host, who respects your privacy and a reasonable price for Amsterdam. Not super clean and cozy but acceptable. Thank you, Virginia! :)
