It was the first time I felt like home being in a trip.
Sparkling clean, ideal location in a picturesque street (if you prefer walking to using public transport, it will take you ~20 min to get to Opera), quiet place, and Debbie is the most welcoming host I've ever met. We arrived shamelessly late at night, and she did everything so that we can have proper rest.
Best place to stay in Oslo if you ask me. Strongly recommended
