Me and my girlfriend stayed at Flavio's house in the amterdam new suburb of Ijburg and had a very surprising wonderful experience. For amsterdam the house is a bit far away from the center, 10 minutes by Tram and 20 minutes by bus, but Ijburg is a very modern and pleasant area, very different with a much different architecture form more traditional areas.
In tipical amsterdam style, Flavio's house doesn't have eleveator but very steep stairs which since the room is in the last floor can be challenging if you have a lot of luggage. But those are minor problems since Flavio is a really friendly talkative host who made us feel at home immediately.
He provided us with tips for a great Indonesian restaurant where to have dinner, a great place to see the NYE fireworks and even a great coffeeshop where to go... He also provided free coffee and some headache meds. In general a great guy and host that helped our experience in Amsterdam to become more unforgettable!
I highly recommend his house to anyone and
