My wife, baby and I had a great three night stay at John & Ceca's spacious apartment. It's perfectly situated to explore the best of Brussels - we were able to walk everywhere. As others have said the lift in the building is very small but we were able to squeeze our buggy in there - just! Though there are some additional steps to access the apartment floor so not suitable for anyone looking for 100% step-free access.
If you stay here and like beer you need to visit our favourite bar - Moeder Lambic - just a couple of minutes walk from the apartment.
John was very helpful before the trip, check in was a breeze and I would not hesitate to stay here again.
