Nice place, poor communication. We waited outside for over an hour because the door wouldn't open and he was unresponsive. Delayed communication was a recurring theme in our conversations, do be warned.
It is very near the tram stop but feels like a sketchy neighbourhood. The place itself is significantly better. Clean, bright and open. Nice, spacious place with pretty decor and a great bed. Looks just like in the photos, you feel like a million bucks! The fridge stank though, and the aircon was broken so it was hot. Also quite noisy outside, so it's not ideal to open the windows overnight. We got a set of four different keys for our stay - not sure whether to feel well protected or concerned that our neighbourhood requires so many locks. Also, if you're getting the master bedroom do note that the frosted window leads directly to the patio, so it can feel rather exposed.
Very easy to get around Brussels from his place. There are some nice boulangeries in the area, too - I recommend Distra, it's nearby. Grand Place is also within walking distance (the map says 1.2 km but it feels shorter than that). Overall an accessible location and cheap price, but be warned about communication / the neighbourhood.
