Location, location, location, really perfect in the center without the noise or trouble of people and traffic. Be aware that you have to walk up 3 stairs. I found them very easy but after long days of walking or biking it could be hard for some.
The apt is very handy layed out. Functional kitchen but small with dining area for 3/4 people. Bathroom more than fine, all necessary appliances available. Two bedrooms that feel really spacious, one soft bed, one firm, nicely and well decorated, easily makes a home away from home.
