One of the best Airbnb I've ever stayed at. Terrific location next to the Round Tower; near several coffee shops, restaurants, bars and a grocery store (the nearby Norreport metro station is a 20 minute ride from the airport on the M2). Very clean apartment with lots of space; two large bedrooms and a massive shower. My sons slept in the bedrooms and I slept on the big, comfortable couch. Great communication with the managers who were quick to respond. Having a door code instead of a key is bonus as well.
If you have trouble climbing stairs you may want to reconsider since the apartment is on the fifth floor, but this wasn't a problem for us.
A fantastic apartment.
