I had a wonderful experience staying at Michael's place during my 10-day-stay in Stockholm. The location is pretty much unbeatable, as you are at the very heart of Stockholm and everything is extremely easy to reach from the historic and picturesque island of Gamla Stan.
The apartment and room itself were exactly (I would argue even better) as expected - the apartment was super clean, everything you might need was there and I felt very welcome and comfortable from the very start.
Michael was extremely forthcoming and while we didn't see much of each other during my stay due to our schedules, he made me feel very welcome and was lovely to talk to when we did. Checking in and out was a breeze as well!
I can't recommend staying at Michael's enough - I would do so again in a heartbeat and will be recommending him to anyone who cares to ask. :)
