The biscuits provided were very nice. The apartment has a nice kitchenette. There is a comfy table and chairs to eat at. The check-in process is excellent and the apartment is easy to find and close to public transport and the heart of Brussels. The access stairs are very narrow and if you have a large heavy suitcase this would probably be a bit tricky.
Note: the bed is a sofa bed and not such a comfy one.
If you plan to stay in Brussels and want to go out all night and can sleep through the roadworks that are actively in progress right under the apartment window, that you need to open because the heater will not turn off and it is too hot then this apartment would be a good choice.
Do not forget that the leaky toilet will be managed by the cleaner putting an ice cream tub under the leak, which will fail to capture the majority of the water, but do not worry too much because you can happily catch all the water on your shoulder when you sit on the toilet, better still you could sit and hold the ice-cream tub and then at least the water will not drip on you or the floor. And then you can reflect on your situation and start to realise that the toilet leak mentioned to you a few hours before your arrival is not a toilet leak (at least not yours!) but one from the apartment above, which was almost certainly known about before the day of your arrival and is also noted in other reviews should you scroll far enough down the review list.
