I was very impressed and happy with my stay at Beca's!
She is such an interesting and kind person, who offers both recommendations of places to go as well as a private room with all the facilities one could possibly want and need. I was staying there during a heatwave, yet this was no problem at all since the room has airconditioning and other cooling facilities. Beca has really thought of everything in detail, the apartment is only a brief tram-ride away from the city centre and she is a lovely and welcoming host, who also respects a closed door. I truly recommend that you rent this place, if it's available. I would myself love to stay there again, next time I find myself in Amsterdam :-)
