The studio is exactly as Pedram and Pegah describe in the announce. It is a little far from the centre of the town (kind of 30 minutes) but well connected (you only have to take one bus). It is small but had everything we needed.
Pedram and Pegah are great hosts, Pegah checked us in and she was so nice and also very fast to answer to all of our questions.
Totally recommended for a short and non-pretencious stay in Bruxelles!
