Strictly speaking this is not related to the Amsterdam forum but I thought I'd share the fact that I used www.airbnb.com for the first time this weekend to book a two bed, two bath apartment (In Cardiff). I only resorted to this as there were very few hotels available and those that were, were asking extortionate prices.
Have to say I was very impressed. We had a fantastic place in a great location. Everything from the booking through arrival and the facilities we had was spot on. The description of the apartment on the website had been spot on.
I will certainly use them again and have no hesitation in recommending them.
