I have spent 2 weeks at Michael's place and found them pretty enjoyable. The room itself is not big, with the only window giving onto the internal "well" court of the building. However, the living room is shared and has a great view, and it compensates well for the internal window of the room. Note that if you plan to work, the table in the room may be too small for that purpose, but I am sure a solution can be easily found with Michael. Note also that there is another room for rent in the same apartment, so you most likely will be sharing the living room and the kitchen not only with Michael but with another 1-2 guests as well. It personally did not trouble me, but I believe some people may be sensitive to it (especially since there is no lock on the room door).
Interactions with Michael were very fluid and he was always able to find a solution for any need I would have. Overall, I find, this room was good value for its price, the view is great and the host is very welcoming. I recommend.
