Better to be aware that you're not going to share the flat with the landlord, who's often away, but with the TENANT, who's actually very often/always in the flat. So, in this respect, I found the instructions given on the website very misleading. Also, I was asked to leave my shoes at the entrance but the carpet was definitely not clean.
Other than that it's worth saying that Hussein is a great guy I had fun to talk to and he really is a great host making you feel comfortable.
