The place was great: excellent location in the heart of the EU quarter, lots of supermarkets and cafes around, close to the main metro station Schuman as well as the direct bus line from/to the airport. Very clean and modern studio, and the heater really warmed up the room.
The only minus point was the wifi internet: the connection was really weak/unstable I could not do my flight check-in for next day, nor get in touch with the owner to ask for a flexible check-out.
Still, would reccommed! Thank you.
