Great communication with Finn, easy to follow instructions, about 10 minutes or less walk from multiple stations (depends where you come from, we came from rosenthaler platz), amenities are basic necessities but everything is in good condition (the washing machine is in the apartment itself, bonus points from us! Although a laundromat isn't far too). As a lot of people noted the stairs can be a bit tiring but it's totally worth it for the location, security and overall hospitality. We didn't use the kitchen apart from plates/cups buy there is kettle, stove, toaster and fridge. Heating is good, wasn't too hot whilst we were there so not sure how that impacts during summer. So many good restaurants/shops around, and our first night we saw many retail shops were open late. You can actually walk down to museum insel/alexanderplatz (we did, but it is about 30mins).
