I would give this place a 6th star just because of the location. Great spot for a tourist, about a 2 minute walk to the main square at the Grand Palace.
The apartment is on the corner of the block, with a nice view of the street and sunshine in the apartment throughout the day.
It was on a busy street, very popular for tourists with a lot of places to eat, so there is a little bit of noise in the evening, but nothing to be concerned about.
It was the closest spot to Central Station that was in the main bit of the city centre, so you don't have to carry your bags too far when you get there.
Also, there is a laundromat around the corner so you can get some washing done if you need to.
The apartment is located on the 2nd floor. The stairs are a little steep, it was a workout getting my bag up to the room, but most of Europe is like that so it's just something you need to accept.
Inside the apartment, it is well decorated. The kitchen and living area are a decent size, and the bedroom had a spot for my bag so it was out of the way. The bed and pillows were nice and comfortable.
Cable TV was good, the fridge kept my drinks chilled, and the iron with ironing board came in handy.
The bathroom is small, room for one, but again this is typical of Europe. Water pressure in the shower is good.
Overall, it was an excellent apartment in an excellent area and I had an excellent stay.
Thank you Antoine. This made my stay in Brussels even better.
