Lotte was a great host (even though we didn't meet her in person). When we arrived one of her friends awaited us and showed us around the house. Lotte provided everything we needed up front (lot's of useful information about Amsterdam, a hairdryer we asked for,...) and welcomed us with some beers in the fridge and traditional dutch cookies. Her flat is awesome and really nice decorated. You feel at home from the very first moment. Everything is clean and tidy.
I'd definitely recommend to stay at her place and we will come back if we visit Amsterdam again!
Thank you very much :-)
