Spacious apartaments on the second floor of a 100-year old house. No elevator. Quiet street, windows face closed small yards inside the house. No views, no balconies. All windows can be opened. There is a heating system, but no air-conditioning. High ceilings. Apartaments have good old wooden furniture together with some modern IKEA-style items. Big double bed comes with two separate mattresses, feels almost like one big mattress. It is clean and comfortable, the host offers extra linen freely. The bedroom has a window and a wardrobe, it is connected by a door with the main room. The kitchen is perfectly equipped: it has a gas stove with an oven, a big fridge, a dish-washing machine, a kettle, some coffee-machines and lots of utensils. Note that the kitchen is quite small and you have to eat in the main room. Bathroom has a good shower cabin (which misses a shelf), all equipment is modern and clean, works fine. Also there is a washing machine (which we did not use).
Summarizing: the apartaments are quite old and do not look like a hotel. But everything is clean; bed, kitchen and bathroom have good modern equipment. It is a nice place to stay and feel the atmosphere of a good old Vienna house.
