We spent 5 nights at Doerthe's and it was great. Clean, friendly and easy to find, and there were nice touches like snacks and a bottle of wine! The surrounding neighborhood was wonderful- we ate breakfast and dinner in the neighborhood every day. There was even a local street fair in the neighborhood the weekend we were there.
Easy access to two U-bahn lines as well as buses- Doerthe's place had it all. Highly recommended!
