The place was lovely and homey, we booked the space for three people but I can confidently say that it is comfortable for four people. Everything is clean, the duvet smells nice, the kitchen is very convenient, completed with its own sparkling water machine (!) and it even has a lovely backyard. The neighbourhood is lovely and quiet with pretty colorful wooden houses around the area. Location-wise it is also easy to reach - even for those who has never visited Oslo. There's a nice park near the area, some pubs, and several grocery stores, so we could easily get our ingredients for cooking, and save some money for other stuffs, considering Oslo is an expensice city.
I know that I've given many praises, but I have to say that the absolute gem is the host herself - Emma June is a total superhost, she's very friendly, bubbly, flexible and helpful to us with her tips and suggestions. Thank you Emma :)
