Would absolutely recommend Ras Residence to visitors to Brussels! The staff were incredibly friendly and accommodating, and our room was perfect for the two of us (albeit a bit small). Room was clean, washroom was clean, linens fresh, toiletries provided. We were very comfortable the entire time. Bed was a bit firm for my taste, however ;)
Location was fine, approx 15 min walk to centre, but many sights to see along the way. We did not need public transport during our short 3 day stay.
10/10 would come back.
