I stayed for a week to spend time with a local friend and to explore the city by bike. The Oderberger is a hotel built around a former municipal indoor pool in Prenzlauer Berg, a lively part of town a little north of the center. While the weather was warmer than expected, it was still pretty cold, and going to the sauna after a few hours outside was perfect. The room was clean and warm, with a brick wall, wood floors and some exposed timbers - much nicer to me than many sterile hotel rooms. Rental bike was in good shape. Covid discipline was taken seriously.
