The stay in Sietskes flat was perfect. When we were coming in, she prepared everthing really cute that you feel very welcome. The flat has a lot of space also for four people. Sietske was very attentively, gave us very helpful recommendations and answered very quickly. If you need any help, it is really good organized in the building, so you could ask the neighbour all the time. It is a bit farer away from the center, but it is so nice to go by bicycle. To come into the center, you drive through the Vondel-Park, which is like one of a sight from Amsterdam. Every local is driving bicycle, so you really have to do it as well!! I highly recommend a stay in this flat in Amsterdam.
