Don't get impressed by the stairs you will need to climb to get to the top floor... The studio is exaclty as it looks on the pictures, very clean and full of interesting stuff - the Lego head was awesome! :-) It is around the corner from the Manneken Pis and 10 mins to the central train station - very useful since we had an early morning flight back!
Kike was a fantastic host and, although my boyfriend and I had the chance to meet him only at our arrival (we had only two days and wanted to make the most out of them!), he was available to help and very friendly. He provided a useful and detailed guide on suggested places to have breakfast, lunch and drinks - we tried a couple and enjoyed them very much.
Staying at Kike's place has made our short (and unfortunately rainy) trip to Bruxelles very pleasant and we highly recommend his studio!
