We, a family of four, stayed for about one week in Trongs appartment in Brussels in August 2022. The description was accurate, it was spacious, very clean and accomodating. We had to take care of the resident cat - but everything was provided so it was very little work for us. Our kids enjoyed playing with the cat and she is very famliy and child friendly.
During our stay it was very hot in Brussels (30 degrees plus) and the top floor of the appartment got hot. But the sleeping rooms downstairs stayed comfortable.
The appartment is next to numerous public transport stations and so it was easy to reach the center of Brussels and other destinations (like the Atomium).
We did not meet Celine and Trong in person, but we received very detailed information about where to find the key and how to handle various things in the appartment. When we had a question, we received quick replys via text.
We fully recommend a stay in this appartment if you want to visit Brussels.
