Micheal's apartment is located in a nice neighbourhood, only 20 minutes walking to the centre. If you are working at the university the location is perfect, since you can reach many departments on foot in 10-20 minutes. There is also a small supermarket just outside the door, and many other shops, bars and restaurants nearby.
The building is in front of a U-bahn station and a street with lots of traffic, so it could be a bity noisy, but I personally had no problem in sleeping.
The room is compact but nicely furnished, bright and ventilated. The kitchen is functional and has everything you need to cook complete meals.
The wifi signal reaches uniformly all the areas, but may be sometimes unstable. If you make a videocall you might lose connection for a few seconds, but besides that it didn't create me any problems.
Micheal works every day in the shop downstairs so he is always available to solve any kind of problem. The check-in is extremely flexible: you can arrive at any time, also in the night, and you can get the keys from a small safe, locked with a secret code that you will receive in a private message.
