Our stay at Gavriel's was very good! It was reasonably priced, and has nearly everything you could want - a mini-fridge, wifi, a well-stocked kitchen, extra blankets - in a reasonably-sized space. Check-in was easy, and communication was strong.
Our comfort was middling, but everything is clear on the listing. There is no AC, so we cracked the window during the day, but didn't feel comfortable doing so at night on the ground floor. Pull-out couch was reasonably comfortable, and pillows were slightly lacking. But space was abundant, and extra blankets were provided, which helped!
For us, the location was not ideal. We did not care for the shopping nearby, and it was a decent walk from Grand Place with minimal options for transportation to get us there.
But in general, Gavriel's listing provided great value!
