Myself and my friends stayed at Martinas place during our trip to Amsterdam. We didn't get to meet her but arrangements were made very easily to get the keys. The Apt is very central, within walking distance of everything. It is such a unique place and we loved it. It was clean and tidy. Joepy their cat is very friendly and that's from someone who isn't a huge cat lover but he is adorable. You have to know, that he lives there but is very harmless. All in all this was a perfect stay.
