Martha's place is just incredible. You couldn't wish for any better. Super easy to get there from the airport. It's super central, lot's of things are walking distance. It's super quiet, you can make sure you'll sleep like a baby. The apartment is extremely beautiful with a lovely view. Supermatkets and coffee places within couple of minutes. Marthe was away I only meet her at the very end of my stay. She's super nice and very helpful, communication was perfect. It was my first time in Oslo but I'm sure I'll be back.
