Good place to stay and to visit Berlin from. Reckon with a 10 minutes walk to the station and about 35 minute by S-Bahn to City Centre (Friedrichstrasse e.g.). S7 runs every 10 minutes which is convenient. House has all the basics. Sleeps four: 2 person bedroom, plus a living with a sleeping couch for 2 persons (or one of them on the foldable guest-bed).
Shower and kitchen are ok. Washing machine works fine.
Pool is nice. It is close to where the owners have their own seats, when they are sitting outside. But that is totally undisturbing. Very modest, nice and open people, ready to be of assistence whenever they can.
