We stayed at Jens' place for 2 nights over a weekend visit to Stockholm and it was perfect for us! Jens is lovely - very quick and helpful communication, we picked up the keys from him in the centre of town and he gave us some good recommendations about what to see locally and where to eat and drink.
The studio itself is very well laid out for a small flat with everything you could need. The bed was comfortable and we had a good nights sleep.
The studio is in an excellent location - only 5 mins walk from Hornstull tube/train which made it very easy to get around stockholm, also there is a useful bus stop directly outside the flat.
Overall we definitely recommend Jens to other AirBnB users - it is a great base for exploring this wonderful city. Thanks for the stay Jens!
