Frank was a very kind and attentive host, but there are some aspects of the flat that aren't ideal and seem to be out of his control. Frank did a great job of communicating how to pick up keys and gain access to the flat, and checked in to make sure everything was fine. The issues we faced were regarding Internet access and the immediate local environment. The apartment has wifi, but it was super spotty and when it did work was not fast enough to use for anything more than basic webpages. Frank really tried to help us fix the problem and even stopped by to test it on his own devices (we weren't home) but it did hamper our ability to plan activities and communicate online. The location is indeed central to many tourist sites and cool neighborhoods, but the immediate area around the apartment is pretty sparse with regards to restaurants and places to visit. There's a UBahn station not too far off, but getting anywhere involved a 10-15 minute walk along a multi-lane thoroughfare. Nothing against Frank, but not sure the apartment is perfectly suited for millenials who need wifi to live and want easy access to restaurants and bars.
