Flat is in a good location, especially if coming by train, with lots of things around. Really good air con (very appreciated during a heatwave!) and flat is larger than you expect. Communication with the host fairly good, and Olivier and PJ are very nice, but there was a bit of confusion over a late check-out.
Sleeping was difficult - there’s a tram going by outside until 1am and starts up again at 6am, and there’s too much light coming in from the terrace door. We stayed during end of June so during winter this is less of an issue. There’s also a lot of noise from a downstairs neighbour and the front door of the building. Also there was a funny smell from the bathroom with some flies around that could do with being addressed.
Unfortunately we would not recommend staying in Olivier’s place - it just wasn’t for us. Totally recommend Antwerp though!
