We had a very pleasant stay in Katrine's penthouse. Katrine really was a great hostess: she helped us with very detailled travel information, was very quick to respond and follow up communication.
The penthouse was really comfortabel for 4 people. Nice clean bed sheets and towels were provided. Also kitchen was clean very suitable, although very basic in equipment.
The penthouse is very accessible with public transport, close to the center and yet very quiet neighborhood. We recommend absolutely!
