About 10 mins walk from the main train station, a similar distance from all the stuff you probably want to see like the Cathedral and all the palaces.
A double bed in one room, a single pull-out bed in the other. Not luxurious, but functional and clean. Good shower. Laundromat, supermarket, good restaurants are all 2 minutes down the road.
The host gave us a list of places to go/see, which were all great. He seemed nice enough, meeting us for check in but staying out of our hair after that.
