We did Airbnb for our entire trip, which spanned multiple cities, and we loved Markus' flat the best. It was extremely spacious and exactly as pictured, in a beautifully restored historical building. The bathroom was a bit quirky in the sense that the toilet was in a separate part of the flat from the shower, but I think that is common for old buildings that are converted into flats. All the fittings etc. were modern and there was a washer as advertised, which came in quite handy. Location was prime - right along the river and an easy 10-15 minutes walk from the main sights. We walked 99% of the time. but for the 1% of the time we wanted to take public transportation, the subway was right across the street from the flat. Ride to the airport was easy breezy as well as the airport bus picked up on the next block. Markus also has a large cabinet stocked with things like guidebooks and maps and brochures, which makes things easier for visitors who want to sightsee.
