Nice cozy house in a pristine quiet area with interior planned very well, strongly recommend staying here, cozy rooms suited for a couple and a child. Check out amazing book collection in the house, kid's room stocked with games and books and a playground right outside is a delighter. Anita is a good host, with prompt response on anything.
Good connectivity from Holmlia station with 7 min walk with luggage from station towards Lerdalstoppen, and connects to city downtown in 15 minutes. Take Oslo transport pass as you can use on trains, buses.
Weekend train schedules are less frequent and starts late 8am on weekend, incase you plan for early departure - check timetable online, else cab is expensive.
