The apartment is well located near EU institutions, close to metro and shops. It was very clean and recently renovated.
It is at the second floor with narrow stairs so it could be difficult with heavy baggage. The WiFi is very slow, and the WiFi security is poor when it works
There were welcome gifts, like coffee, tea, and sweets that was very nice. The lack of towels in the kitchen was a bit of a struggle but manageable.
I would recommend the place for the location and for its good state, if you ok with not so good aspects.
