We stayed in Ravianne's place during a conference. The location was excellent, only 15-20 minutes away from RAI conference center by the tram. Ravianne's place is just a couple of minutes walk to the tram. There are plenty of good restaurants within 5 minutes walk. The famous food market (Foodhallen) is the next block to the apartment.
The apartment has everything you need, even though the apartment doesn't have TV we didn't even miss watching TV; but just in case I had Netflix in my tablet.
Ravianne was very fast in any communication with us and able to solve any problem very quickly.
I really recommend her place for a stay in Amsterdam.
