The location of this apartment is superb. The apartment itself is reasonably spacious and well equipped. As most guests I have noted You do have noise from the café directly underneath you but once you go in the bedroom and shut the doors you don’t hear it - just normal apartment building noises. For me it wasn’t a problem as I was out for dinner or concerts every night but if you’re traveling style is to come home at the end of the day have dinner in the apartment and then sort of chill out before bed it might be bothersome. Also as noted by many guess if you have trouble the stairs this is not the apartment for you it’s only up one flight but it’s a steep flight with rather narrow stairs. That said if I went back to Antwerp I wouldn’t stay any place else.
One last thing if you’re planning on arriving by taxi or Uber be sure to get the nearest intersection where they can drop you off since the apartment is on a pedestrian street you will have to walk one block to get to it
