Josef's place is great, very close to the center and the tram. it's also close to the metro station and a mall if that's your thing. it's clean, quiet, warm in the winter and the TV is big and amazing! Bed is nice and comfortable but could use a bigger blanket instead of 2 small ones. kitchen is well equipped, couch is comfortable. There's nothing bad to say about the place.
Josef is a great host, responsive, polite and helpful, he also gives discounts to some restaurants.
highly recommended!
