We stayed at this apartment for a long weekend, and really enjoyed our stay. While located maybe 50 meters from the Grand Place, the apartment is located in the back of the building, so it is very quiet. We found a few good supermarkets within a short walk, and of course there are lots of restaurants and beautiful sights nearby. Walking from the Central train station took less than 10 min with our luggage.
The bed was firm but comfortable, the shower had plenty of hot water, and the sheets and towels were nice quality.
The kitchen was outfit with all the cooking basics, and the cookware especially seemed new and updated.
There was plenty of comfortable seating for two people and a lot of space to spread out. The decoration of the apartment was a bit exotic and interesting, and was a nice relief from the plain white walls of other places.
When we were there, the AC had recently broken and was not going to be repaired for a while. If AC is important to you, check with the host before booking. The host did provide a very good fan and offered a couple free drinks from his restaurant downstairs. The fan helped immensely, and we appreciated the offer and the drinks!
The host lives in the unit opposite this one at the top of the stairs. He was very friendly and checked on us a couple times to make sure all was well.
Note that there is a fairly long flight of somewhat narrow steps to get to the apartment, and then another flight inside to reach the upper level with the bed and bathroom.
This is not an ideal place for remote work. The only work table is the dinner table, and you would need to use an extension cord (provided) to reach a power outlet. The wifi speed measured around 4MB up and down, which worked for email and light web browsing but would not suffice for a video call. The owner is aware of this and said he was working on getting a better connection. So, if you are interested in the place and need high-speed internet, then ask before reserving.
