Monica was great at communicating with us about our stay and made "check in" very easy. Coco the tiny dog also welcomed us and was very cute! The location, we found great with easy access to tramways and the U bahn metro which are 2 mins and 10 mins walk respectively. There is a good local beer restaurant 2 mins walk and a spar supermarket for all your needs. The clean, small studio itself consists of a toilet, bathroom and sofa bed which we found comfy enough after a long day on our feet exploring Vienna. The room does get hot when it's sunny during the day and with windows open at night it's loud outside because of the tram so i'd recommend ear plugs if staying when it is warm. Otherwise the studio has a microwave, a fridge, a kettle with coffee and tea but no other cooking facilities should you need them; we only stayed 2 nights so did not require them.
Overall we enjoyed our stay at Monica and Wolfgangs, although we did not get to meet Wolfgang. Monica seemed like she'd help in anyway that she could and being next door in the connecting flat made it easy to contact them. Danke!
