I stayed at Marianne's with my husband and brother-in-law. The apartment is spacious and is just a short walk from the tram stop making it easy to get to Amsterdam Central. Marianne welcomed us at her apartment with stroopwaffle and wine and gave us a tour. Marianne had also left a list of useful information about her apartment and things to do in Amsterdam.
If you are not looking to stay in the centre on Amsterdam, I would really recommend staying at Marianne's. It's 10-15 minutes on the tram which stop at least every 10 minutes and the apartment is really peaceful.
