The apartment is in a fantastic location for seeing everything in Brussels and John and Ceca are great hosts! The communication was really good and they were on hand to answer any questions and queries before the trip.
The apartment is one or two streets from the Grand Place which means it can be loud at night (we stayed on a Friday and Saturday night). Earplugs were provided in the bedrooms however which meant it wasn't a problem sleeping.
I would highly recommend staying here! An ideal spot for exploring the city.
