Ramez's place is excellently located a few blocks from Hbf (train/u-bahn, and s-bahn), and an easy walk to attractions in the city center. Ramez's son met us in person and showed us around the place. The apartment in well-appointed with additional touches not seen in a lot of airbnbs (lots of tea and coffee, some basic spices/oils, basic toiletries). As some comments mentioned, there can be street noise because the unit is in a busy area. However, we never noticed it at night, only in the morning when local small grocers were receiving deliveries or on trash day. I don't think it would be bothersome unless you're extremely noise sensitive. I had a question during our stay and a slightly late arrival due to a train delay and Ramez's responses were immediate.
