Martina was very helpful - she met us at the flat at check-in time and gave us two keys. The flat was perfect for our family of four --- a pull-out bed in the living room for the kids and a separate bedroom with large bed for us parents. The location was great --- we could walk to the major museums and museum quartier, and go to hipster restaurants near the flat. Actually, the area directly around the flat seems like it could warrant another half day of exploration - we saw a lot of funky shops and cool eateries but didn't have enough time to properly check them out. I liked how the apartment was furnished - simple, with some antiques and some modern pieces. Incredibly high ceilings! And very quiet. It faces an interior courtyard. The fridge, cappucino machine, and fresh towels were very welcome. Thanks, Martina!
