The house is nice, well located, and even luxurious for Brussels standards. The heating works perfectly, which is a big deal in this country.
The room itself is very pleasant and well equipped, and Leo is a helpful and flexible host.
My only problem is that Room 4 is above the kitchen, so you are not supposed to use the kitchen (and the dining area, which is the only place in the house to chill outside your room) after 10 pm. I can accept this but I would have appreciated to know in advance. Also there was no info about the morning and I was afraid every day that I will disturb a guest sleeping up there if I make breakfast before going to work. The walls are really thin, so you have to be considerate with each other.
If I was the owner I would probably convert the gallery where Room 4 currently is, into a chill lounge for all guests, and give 24/7 access to the kitchen.
