Absolutely superb apartment in a fantastic location for all the sights of Brussels. The apartment is in a beautiful old building and has a great balcony for when you need a bit of chill-time above the ground.
Florence replied promptly (often within minutes), check-in was easy and well explained and the place was certainly large enough for four.
Great quality for the price (we came for the Tour de France and Florence kept the price the same for that weekend despite probably being able to command the double).
Highly recommended.
