Flori was very responsive and friendly. She worked hard to get us into the apartment earlier than the posted check-in time, which was very appreciated! The apartment was clean and comfortable. The elevator to the second floor was convenient with our luggage. The location was fantastic... away from all of the tourist noise and about a 10-15 minute walk to Grand Place and all of the shopping and restaurants there. There was also a local chain bakery, Paul, just down the street that was perfect for coffee and a light breakfast. It was just a 5 minute walk from De Brouckure train station, so an easy 4 stops from Midi.
Would I recommend this flat? Absolutely! Like I mentioned it was clean, Flori was great and the location was superb.
A few items to note: the shower is literally in the bedroom, which could be awkward for travelers who aren't 100% comfortable with each other -- the toilet is private, but opens up into the small living area. This didn't bother my boyfriend and me, however, it is something to be aware of.
Also, we used Uber a couple of times during our short stay and had great drivers and the service was very reasonably priced -- about 6-8 euros to get to the Grand Market area. It was POURING rain while we were there, so walking wasn't always a great option.
If you are looking for a clean, cozy, easy, centrally located place in Brussels... you have found it!
