Our stay here was as expected. The apartment provides ample space for two adults and is comfortable. Proximity to train station is nice. We attended Fruhlingsfest and were able to walk to Theresienwiese which was fantastic.
Several reviews claimed the apartment is in a bad neighborhood, which I do not agree with. Yes, there is a strip club next door and another one a few blocks away. There are not "5-7" as one person claims. I did not enter the strip clubs (perhaps the other reviewers did) so all I saw was the exterior of a building. No naked women outside, in the windows, etc. And we stayed for 5 nights.
You have to go through 3 locked doors to get into the apartment. One door lets you in the courtyard, the other lets you in the building, and then the other lets you in the apartment. It is very well secured, much more so than anywhere I've ever stayed, including my personal home. I would have no problem bringing my family here. I think perhaps some people are "offended" too easily nowadays.
If you're going to Theresienwiese, this is the apartment for you.
