My stay at Michael's studio was overall pleasant. The location is good, near to a subway station and the Naschmarkt. The studio is quite small, but has everything one needs. Perfect for single traveller.
I have never met Michael but he is very fast in replying to any messages and questions I had.
Keep in mind, the studio is in an apartement with 4 different studios, each with there own entrance and doorcode. The code situation was a bit tricky at first but you get the hang of it quite quickly.
Thanks!
