Great location and host. Would stay there again. It's an 'Altbau' so has charm, but also lacks some modern amenities like larger/2nd bathroom, etc. All in all great place. Chris was very responsive. There is a lot of construction in Vienna, so I recommend you check with him on if and what is happening nearby which could create noise and/or closures. Super central though to everything and his local tips for food were spot-on.
