Excellent location, within easy walking distance to the Grand Place (maybe 2 minutes) and Centraal Station (less than 10 minutes). As described in the listing, guests have access to the gym and the spa at The Dominican Hotel. Very nice amenities.
Hans was extremely responsive to messages, both during planning and during our stay. The unit was pretty much as described, and the kitchen has all the basic amenities that you would want. The hotel provides daily housekeeping. It was quite comfortable.
We did experience a couple of issues, however. The A/C unit was not functioning, and the workmen were not able to fix it during our stay. Hans offered another unit within the same building to us. We did not move because we did not want to deal with the hassle of packing up and moving. The temperature was mostly fine because a small fan was available. We also lost internet connection for about half a day, but the issue was addressed as promptly as the hotel/Hans could manage.
All in all, very good value, and we would recommend it.
