Marthe's apartment is in a charming neighborhood in central Oslo, near a university, and surrounded by a diverse assortment of cafes and restaurants. It's also on a tram line, which we made good use of, though it is close enough to the center of town that many of the popular tourist sites are within a healthy walking distance. (The Royal Palace is just a couple of blocks away -- it is surrounded by a beautiful park which is open to the public. It was a real treat to stroll through the park on a bright, sunny Oslo summer day.)
The apartment is in a newer building cleverly tucked in between much older buildings with ground floor retail and upper level apartments. The apartment itself overlooks a private, quiet courtyard in the back of the building. The apartment is both bright and cozy, with a dramatic spiral staircase uniting the two levels within.
We made full use of the dishwasher, refrigerator/freezer, oven/stove, washing machine and shower. All worked as expected.
This is Marthe's home, and there are a number of nice, personal touches within the apartment, which I enjoyed.
Marthe was highly responsive to our questions both before and during our stay.
