Werner was very responsive and helpful. The place is 8 min by foot from Conference center Messe. Metro station is 5 min appart. Next door there is local pub, what closes at 11.00 pm. At night there is quite, so there is possible to sleep well.
The appartment is perfectly clean. Matraces are comfy. Full size mirror in the room. The apartment is at ground foor, so you need to carry you luggage just some 10 steps at the entrance. Good shower.
Hosts are very attentive , so You will feel wellcomed.
