Excellent place to stay, highly recommended. Hugues was the perfect host - rapid responses to any contact, remained accessible during the stay. Met us at check-in, gave clear instructions about the property, and excellent advice about Brussels.
The flat has to be seen to be believed - it is literally a Frites Museum! Absolutely spotless, with all expected amenities. The private garden is also beautiful, perfect for a few beers outside if the weather allows.
We stayed with our 14 month old who is crawling but not walking - the space has a few delicate objects (art, display cabinets) and an open staircase to the basement - it may be worth discussing the suitability for older, more mobile (and inquisitive) children with Hugues before booking.
The location is handy for central Brussels, but you do need to use the tram to get to most areas (10-20 minute ride depending where). They are frequent, and the nearest tram stop is only 2-3 minutes walk away. The bars and restaurants of Saint-Gilles are a leisurely 15-20 min walk or short tram ride. There is a large Lidl 5 mins walk away, and a Carrefour supermarket on the street corner.
This is a unique property in which to stay, and Hugues is the perfect host. I would recommend this to anyone, and would certainly stay again if we head back to Brussels.
