I had a very good and relaxing time in Helena's and Philip's house. The whole house is refurbished and furnished in a very 'zen' manner which makes it very bright, spacious, straight yet comfortable.
The two are also adorable, just follow their advices to explore Brussels (or only the surrounding quarter that you actually don't have to leave at all ;) ). Nothing to add, just make the average of all the other 'ratings' down here and you get the picture.
