Mona's lovely apartment is just as described: in a great neighbourhood, quiet but just a few minutes to shops, cafes, restaurants, a mini market and a bakery plus easy tram and bus stops - though you can walk to just about all major sights in 10-20mins eg waterfront area of Akers bygge is less than 20mins by foot or no 12 tram takes you there even faster. Mona is a warm and knowledgeable host and I'm just sorry I don't have longer to chat with her and see more of Oslo. The room has direct access to the (shared) bathroom which had great water pressure and like the whole flat was spick and span. Mona keeps the flat warm and cosy so despite it being pretty crisp autumn weather outside, it was always lovely to come home. Loved wandering around the neighbourhood looking at the great houses and architecture. Highly recommend the Viking ship museum (bus 30) clustered with several other museums a little further away but worth the trip (maybe 25 mins by bus). An Oslo pass is worth getting only if you are going to cram in more than a couple of museums in 24 hours and Autumn/winter opening hours seem to be 10 to 4pm for most places. A 24 hour bus/train bus pass costs 90nok compared with 30nok for a single trip ticket when bought from convenience stores like navarset or 7/11 (costs 50nok buying ticket on the bus!) so can be a better option if you don't want to see lots of museums. Though the choice of museums is amazing. I would definitely recommend Mona's home as a great base from which to see Oslo.
