We had a great stay at Manuel's place. Very clean, minimalist room with a sink and shower inside of the bedroom. The toilet is actually just outside the room two feet away, so it was very convenient. We actually booked this last minute after a different place we had booked canceled on us. Manuel was prompt to respond to us and very friendly. We were let in by his partner and it was a very seamless process. We received physical keys to the front door and the bedroom. It is on the second floor so keep that in mind if you have trouble with stairs or have lots of luggage. I would have preferred coded door locks to make check-in easier for guests (and because I lose keys), but his partner got home the exact time we did so it wasn't a problem for us.
The nearest bus stop is a 90-second walk from Manuel's place which was helpful after a long day of walking. It's about a 10-minute walk to Schuman station which is the train you'll use to head to Brussels airport direct without a transfer.
