We had a nice time at Erez' place! Booking was easy and communication with the hosts was fast and friendly. Arriving late was not a problem as the keys were deposited in a lock box. The apartment is nice and well located in a lively area of Berlin, but the next U-Bahn station is about a 10 min walk. We found everything we needed (towels, coffee, etc.).
The hot water boiler is a little small for two persons, but if you hurry a little it's just fine.
Thanks for the nice stay!
