Cool place and a very responsive host.
The place is actually more spacious than photos show it to be, quite comfortable for a short and especially for a bit longer stay - all you need to make good coffee, breakfast or lunch.
Some neat supermarkets nearby plus two late-working places to eat, plus 2 gas stations with 24-hour shops.
A number of public transport nearby - bus stations are close, trams as well, S Bahn is a bit far (15-20 minutes walk to the Mahlsdorf Station) but extremely neat if you want to get to the centre.
Be prepared for the long rides - Mitte, Kreuzberg, Neukölln, Friedrichshain are all 40-50+ minutes away by public transport. If you’re OK with a little travel to and fro, this is your place.
