Catherine's place is amazing. It is exactly like the pictures, very spacious for two people and modernly remodeled. It has a fully equipped kitchen and bathroom. Catherine was very responsive, gave clear instructions for check-in and other enquiries. We picked up the key with no difficulty.
The place is about 10minute walk to the closest metro station - Louise; not super close to the main tourist areas but acceptable. We walked most of the time, about 30-min walk to Grand Place. The neighborhood was fairly quiet, we could hear cars from the 4th floor but did not bother us.
Overall, the experience was wonderful, highly recommended!
