Great location, convenient to public transport and attractions. Lots of food nearby, a great open-air market on the weekends and a supermarket (Delhaize Flagey). In-unit washer/dryer is great, kitchen was well equipped for the basic meals I was making.
WiFi was slow, as others have mentioned. I also found the shower a bit of a pain, what with the water direction being perpendicular to the tub.
For a few nights, highly recommended!
