Tom is a great host! After the check-in, and realizing that we were too tired to go out in search of a restaurant/supermarket, Tom offered us some of his dinner. And, although tired himself, he gave us a few useful tips on Berlin.
The room is confortable and cozy. The only minor inconvenience is the kitchen size, making it difficult to use it.
The apartment is a bit far from the center to go walking, but very near from an S-Bahn station that gets you there in 10 min.
We also had some interesting conversations with Tom and his friends.
Would highly recommend!
