This is a wonderful place to stay, and I would book again. Please read all of the comments before booking to set up for your expectations. We were a group of 4 members, the space was delightful. There are 2 floors of stairs to climb, which were a bit tricky, spiral type of staircase. The front bedrooms can be a bit loud, in November 2019 there is construction across the street, and you do have the bar noise in the evening.
This place is right in the middle of the touristy area of Old Towne, which is wonderful if that is where you want to be. It is also just a few blocks from the metro, 1 stop away from Central Station.
With all of that being said, the place is absolutely wonderful. There is plenty of space for people to have their own area, to wind down and have quiet time. Full kitchen, dining room area, and common area. The 2 bathrooms were fabulous!
Communication with the host was good, straightforward for an AirBnB host.
Have a great time in Stockholm!
