We really loved Pedro's place. The check in and check out were flexible and Pedro met us just as we arrived (with a few suggestions on where we could get some dinner as we were starving after the trip).
The place itself was really stylish with amenities and all. Comfortable bed, nice shower and bathroom. I put myself to sleep with Netflix accessible from the smart TV. No kitchen sink or stove, but Berlin is full of great cooks.
The location was good, it is based in a quiet and well taken care of part of Berlin. The public transport is excellent in Berlin so there was no trouble getting to the busier parts of the city any time of the day.
All in all it was a great stay. Would definitely recommend to any couple who wants a nice private place while staying in Berlin.
