We had a really pleasant stay in Onno's apartment. The studio is very nice, quite big, clean, furnished with everything you might need, and very well located in a peaceful neighbourhood. I could totally live in this place everyday! Everything is at a walking distance (center, museums, bars, shops, ...), we never used the public transportation. Onno was a really arranging host, he even allowed us to park our car on his parking spot after our check-out time. I totally recommend this place and would definitely stay there again should I come back to Amsterdam.
