Jacopo's place is really nice - spacious and comfortable with everything you need (no TV but you're in Berlin, so that doesn't matter). The bed is really comfy and the shower is good too.
We flew into Schoenefeld. From getting on the train at the airport to arriving at the flat only took about 35 minutes. Our flight was delayed and Jacopo was very flexible with checking us in.
The flat is on a nice street, with good cafes, bars, restaurants and grocery shops around the corner. It's less than a five minute walk to the nearest team stop, which takes you to Alexanderplatz in ten minutes. You can also walk from the flat into the centre of Mitte in about twenty minutes.
Everything with Jacopo was really easy. He was happy to share his recommendations for places to eat and drink when we arrived as well. I would happily stay again!
