Martien was extremely responsive and patient. He was kind enough to make dinner reservation for one of the restaurants that only allows reservation by phone.
The place looks exactly like the photo, it’s spacious for two people. The entire apartment was fairly clean. The location is about 6-8 minutes walk to the center, so it may feel a bit dark to walk back at night, especially with small alley ways (though I never felt unsafe in the neighborhood). There is construction right next door, but noise was not an issue at night. Bathroom is equipped with overhead heater and it was useful since it got down to mid 30s during one of my stays. Room also has a small space heater.
Thanks Martien for your hospitality!
