Our stay in B&B Vondelpark was perfect. The room is even better than the photos! Very nice, sunny and spacious. The bathroom inside the room was clean, with a blarge shower and toilet accesories. We didn't book the breakfast service, because there was a Lidl supermarket near the house and we bought some food to leave it in the fridge.
The only bad point is that you can hear everything of the other room (if you have quiet neighbors it isn't a problem, but the first night they were talking loudly..). And the stairs to get to the house were very steep! :P
It is only 20-30 mins from the airport by public transport, and in the same tram stop, you can take the tram directly to the city center in 10 mins. For us, it is a perfect ubication if you want calm and rest (we loved walking through Vondelpark!)
Thanks for all Petra! You care to the last detail to give us a perfect stay in Amsterdam :)
