First of all, Niclas and Robin's place is in an amazing location! It's close to just about everything you need--the train station, lots of restaurants, and even a couple of grocery stores (Lidl and ICA).
There are a couple of vending machines in the building and even a laundry room! Stockholm was our first stop on a backpacking trip so this perk was particularly helpful to us.
Their place is also pretty stylish and is exactly as described and also matches photos.
Thanks for a great stay, Niclas and Robin!
