It was my very first try of Airbnb and it was the best stay of 2016 to me. I travel pretty often and i spend roughly a month/year in hotels. I've been to traditional Japanese Ryokan and to the island resort in Thailand this year and Grégory's place tops everywhere I've been to this year.
His place is very clean, spacious and well decorated. 2 people can have enough private space in his house. His little backyard give you the extra calmness.
Grégory is super nice and friendly. And he knows so many cool stuffs happening in Brussels. His insight was really helpful. He was willing to help all the time and we were so happy that we have him as our host.
His neighborhood is about 30 minutes walking distance from the Grand place but there are so many nice cafes and restaurants around. Also on the way to the Grand place, you can see so many cool places. Uber ride from to the Grand place was around 10Euros.
I can't find anything downside about this place. I strongly recommend.
