Staying at Maria's place (and her family's) was the best thing I ever did. I had no idea that staying at somebody's place for a longer period could be so easy and cosy! I stayed with Maria and her family for two months, and Maria, her husband and their two kids made me feel so welcome and at home from the very first day. The room is great, light, and spacious, the bed is one of those beds you never want to leave, and the apartment has everything you need. The apartment is situated in a quiet street in perfect walking distance from the city centre and (for my case) the university at Blindern. Taking the trigg, t-bane or train (from Nationalthearet) is easy, and the royal garden is SO beautiful in spring. I honostly can say that I don't believe I could have found a better place to live during the two months that I spend in Oslo this spring. I feel so lucky, and I highly recommend you to stay at Maria's place.
