We felt like locals, not tourists, during our stay at Henrik's. You're right in the heart of Gamla Stan, and you can look out over the street life while sipping wine in the living room - it's great! Do note that you'll want earplugs, as you are *right* in the heart of Gamla Stan and there's a good deal of street noise.
Great shower, comfy bed, ample storage space, Nespresso coffeemaker, a washer/dryer combo machine - this all added to the experience.
Henrik was a great host and responded very quickly. Check-in/check-out was a breeze. Highly recommend!
