I would highly recommend Robert's place for your Berlin visit!! Robert was home when I arrived (I was able to check in early) so he gave me a tour and showed me some maps of the area and places of interest. His loft is very cool and our room/bathroom were clean. The waterbed was very comfortable and there was air conditioning (rare in Germany!). We were also able to do a load of laundry, with Robert's help, which was really helpful after travelling for a week. The loft is approximately a 30 minute walk to touristy things (Brandenburg Gate, Reichstag, etc.) with a route through the lovely Tiergarten. You feel close enough to all the action without dealing with the noise and crowds. Robert and Jack (the dog) are so welcoming and I will definitely be staying at their place when I return to Berlin. It is no fluke that Robert is a superhost!
