Great hotel, friendly staff, good breakfasts. Make sure you get a room on the rear end of the building though as the street is quite busy and will wake you up early. Aside from that, everything is a 5 minute walk away, including a great dinery called Magnussons and a "time" convenience store. The hotel has a nice view of the Uppsala domkyrka as well.
One thing they've arranged very well is having everything secured with room keys, including the door into the hotel, so you can come and go as you like even during night time with no problems. In fact, we liked it so much we cancelled our trip to Stockholm to stay at the same hotel again after a short trip to Gotland, and the hotel staff were kind enough to give us the access code to the hotel (since we had to give up our keycards) so that when we returned late at night, we could let ourselves in and pick up the new keycard which was left for us on the desk at reception.
