Kumiko-San is an amazing host. If you decide to stay you get the maximum level of kindness, hospitality and welcoming. Room and apartment are clean, tidy, warm which is important in autumn/winter, private bathrooms with everything necessary and (important for girls) with convenient mirror.
The condominium is situated next to the subway station and if you prefer walking: 5 minutes from the Vigeland sculpture park, 1,5 km from the Karl Johan and National theatre.
And my endless special thanks for Kumiko-San's kindness, for making me feel like I'm home and Japanese tradition food.
I highly recommend this place for staying. And will definitely stay again.
