We had a very pleasant stay at sweet inn apartment.
It’s located in a quiet neighborhood in Ixelles, easy to reach from the airport and easy to reach to central station in Bruxelles or The Grand Place.
The only minor issue we had was with a group of guests from below our apartment which were very loud at 23,24 h in the night, but I messaged the host and they reached in no time to the other guest and asked them to respect the rules.
I have nothing but good things to say about this accommodation.
