Very nice place to stay in Brussels.
Great location, very central, but surprisingly not crowded by tourists. HUGE number of restaurants and other nice places within 100-200 m, just next door (even a tapas bar on the ground floor you can get a drink with an elevator :), no Uber needed. A little bit noisy in the evening (but was OK for me), so you are very sensitive to evening (and also early morning cleaning) noise, double check that.
Very nice apartment, small but very functional. Clean, nice place, easy access and communication. Only point to improve maybe - the temperature of the shower is not very easy control and stabilize, so plan few minutes more for your morning shower, any rush may provoke a cold or very hot water :).
Overally very nice feeling, I would for sure book again the same place.
