We had a wonderful three weeks in this apartment! Stein has been helpful and welcoming, and his little apartment was just big enough for our little family.
The apartment was a lot nicer then the pictures on the web page illustrates. It is not a crowded place, so there is enough space for hanging out on the floor with a baby and for many suitcases.
The location is just perfect! I have been living in fantastic Grunerløkka for 6 years, and can truly not think of a better location. Extremely central, but in a very quiet street, and with a school on the other side of the street, which makes you not having to worry about curious neighbors.
Also, the apartment is in a high first floor which is perfect because people cannot peak in from the street, but you still don't have to worry about walking many status every time you come home.
We have already booked our next stay with Stein in August :-)
