Staying at Julie's in Amsterdam was the best ! The flat is really nice, very comfortable, definitely big enough for 3 people and functional. Everything was perfectly clean and tidy when we came. It might seem a bit "far" from the city center but actually everything is reachable easily (we were on foot the whole weekend) :) But the main thing I will remember is the kindness of Julie, who took the time to explained everything, showed me around on Skype, and checked up on us during our stay. She gave us some precious advice to help us with our trip. Thanks again for everything Julie ! And if you're reading this comment to decide whether or not you wanna stay at her place : go for it ;)
