I had a really lovely time at Eva's - I booked a single room two days before I was scheduled to arrive (last minute trip to Stockholm for an event) and she kindly accepted. I arrive late into the night, and not only had she stayed up to greet me, but she also made hot tea and prepared water for me - it was a really sweet touch!
Her apartment itself is immaculate, and the amenities/facilities she has placed in are what I would imagine seeing in a 4-5 star hotel. It takes about an hour to get from the Arlanda airport to her place (with a transfer at T-centralen). There is a cosy area of shops nearby, where sits a supermarket, kiosk, pharmacy and much more so if you are staying for longer you don't need to worry about travelling far.
All in all, I really enjoyed Eva's place and would come back to stay here!
