The flat was fine. It has 2 floors, the bed in 1st floor was not really comfortable for two people so we slept in the 3rd floor. There is a ladder which could be difficult for some people to climb.
Unfortunately we did not have a warm shower our whole stay, the water was not completely cold so we could have at least a quick shower. The flat can get cold in the night and morning so I recommend to check the weather and pack appropriate pyjamas. ;) Also I could use some warm socks after the shower.
We were provided with all the necessities in the kitchen as well as bathroom.
The location was great, it is only 10 minutes from the flat to the central station by tram. In the city center you can be in 20 minutes by tram. For a quick breakfast I recommend place called Kitchenette, only few minutes by walk.
The communication with Mali was great, she is also a nice person.
While you are in Belgia, I recommend a quick trip to Brugge. :)
