Alexandro was amazing. He had everything I needed and then some. His location is in a perfect part of town with lots of restaurants and bars and in a really nice neighborhood. He was very helpful in providing tips and history about the city as well as transportation and where to go. His suggestions were spot on and well worth listening to plus he lives right next to the bahn system. I highly recommend staying with him if you're going to be in town for a few days or longer. If im back I will absolutely look him up.
