Raul was very kind and helpful, and made it very easy for us to pick up the keys. The apartment (top 22) is in a nice neighborhood, and even though it is a bit old, it was clean and tidy. Moreover, there was a welcome drink waiting for us, and besides the tea and coffee, Raul had bought some food especially for us.
Note that you will need to climb some stairs, even though the building has a lift.
