Overall, the stay was great and we definitely recommend it to you.
To be specific about out stay -- The loft was centrally located and great while exploring various parts of town. Gerrit was extremely responsive and thoughtful -- he checked in amidst our 5 day stay to refresh towels and clear out the trash. Gerrit was also very accommodating, and late/self check in was a possibility.
The loft has simple and slick interiors, and was well equipped with the basics including coffee/tea, some toiletries. Wifi worked well enough for working from the premises. There was also a TV with AppleTV connected. Only two things I'd wished were different -- 1) the mornings were fairly noisy due to construction near by, and 2) the bathroom had a smell of dampness. There's no stove in the loft, but it worked well as we were eating out through the trip.
All in all, we had a great experience and would definitely recommend you try out Gerrit and Veerle's loft.
