My friend and I had the most wonderful time in Oslo at Debbie's place. She is so warm, communicates so promptly and has an amazing space for a great value. Debbie gave great tips on transportation (bus stop just a minute from the place!). When we first arrived we decided to walk from the Central Station to see a bit of the city and it was about 25 minutes. After that we took the bus which was easy.
The amenities in the cottage were lovely. We bought supplies from the grocery just up the street and used the microwave to cook some of the best salmon I've had. The beds were comfortable and the living space was modern and lovely. The upstairs had a space heater but we elected to stay wrapped in the cozy comforters instead.
Debbie also had Netflix and other apps on the TV and we English-speaking gals got VERY attached to the Mesternes Mester show on the NRK app though we did not understand a word of it.
We didn't use the outside patio because it was so cold, but it would be lovely in the summer. We CERTAINLY recommend Debbie's cottage to anyone we know visiting Oslo. :)
