Fantastic - really made our trip.
Location: Could not be better. This is one of the things that makes this a great choice - loved being in the old neighborhood of Prenzlauer Berg. Residential area with plenty of cafes, restaurants, and, for families, playgrounds. Feels very safe and easy to manage. We were able to get to most sites or areas in under 30 minutes either by public transportation or taxis - which come in under two minutes using the Free Now service and are relatively inexpensive compared to other cities.
The apartment looks out on a courtyard so it is not so sunny, but was not an issue for us. We would much prefer to be sitting outside at the wonderful pastry shop/cafe attached to the building.
Great, responsive hosts.
We would definitely book this again for a return trip.
