The flat was exactly as described and the photographs depict it well. It is in a converted attic of a building - hence you do have to climb stairs to the attic level, 4 floors up.
We communicated with Jennifer prior to arriving, and as she was working at our expected arrival time, she arranged that her mother receive us. She explained the amenities in the flat and gave us complimentary water, cool drinks as well as some coffee capsules for the Nespresso machine. She also indicated where the nearest supermarket was for us to stock up on a few essentials. The printed communication in the flat also indicated where a number of recommended restaurant could be found.
We used the flat primarily as a base for discovering Brussels and fond it very effective for that purpose - you can walk to the Grand Place, but you are also close public transport - there is a bus stop near the entrance of the flat.
The double bed was comfortable and ensured a good night rest.
The bathroom has all the facilities but is a little cramped.
All in all we had a great stay in Jennifer's flat.
