Staying at Jaap's was fantastic. The apartment was very well located: less than 5 minutes from a metro station, with a couple of decent places to drink and eat around within 2 minutes of walking, and in a very relaxed area. The apartment was very homey, spacious, and comfy, not to mention the rooftop! Jaap himself was very proactive and attentive during all our interactions, always replying very quickly. If you have the chance, go for this apartment!
