Good location--easy walk into center of town and close to two metro stops--very much enjoyed the Christmas markets and the local area of Maxvorstadt (Cafe Jasmin and VollBio organic market were both highlights). Rainer was in good communication though he was in Madrid...the person who meets you is the cleaning person. The place was not as tidy as it could have been (some crumbs on floor, etc.) but still relatively clean. We had to pay extra to the cleaning person for letting us in because our flight was late (beyond the normal late night check-in fee). Since Rainer is hiring someone to let us in, we understood but it left a bit of a bad taste for us and was not expected (60 euro after we had just paid a taxi 80 euro). Otherwise, the place is a good space (a bit more business than homey) with a great closet on the first floor with views of plants, bushes, etc. from the windows (small sitting space outside).
