I stayed for 4 months in the of Sylvester apartment.
Sylvester is a friendly and approachable man which wants you to have a good stay in Munich. He takes care of the apartment in order easy your stay. If there are any problems you could easily give him a call and it would be fixed in no time.
The location of the apartment is absolutely perfect. It is a 2 minute walk to the closest bus/metro station from which you can reach the city center within 10 minutes.
The apartment itself is quite normal. It has a shared kitchen and bathroom which are ok. There is a refrigerator present, however there isn’t a freezer. Luckily the closest store is only a 5 minute walk which makes it easy to do your groceries.
The rooms itself are perfect. They are quite big and everything you need during your stay is present (towels, bedding, etc.).
Overall i would mostly recommend a stay in this apartment, especially when you have to go for a couple months which makes them perfect for exchange students, internship stays or for a short working period in Munich.
