Fantastic apartment! I stayed here for a month in August and it exceeded my expectations. It's the perfect size for one person.
I had everything I needed and the location is great. Bakery across the street for fresh bread and pastries or a cappuccino, grocery store 1 1/2 blocks away. Walking distance to the Isar or Gaertnerplatz which is lively in the evenings. I felt very safe wherever I went, even walking alone late at night after an evening out with friends. The U-Bahn station is right at the corner and is easy access to the Marienplatz and Hauptbahnhof.
The view from the terrace is fantastic. Imagine having your morning coffee there. Very quiet (I'm noise-sensitive), lots of light from the windows and easy to get a cross-breeze going. This apartment is inside a "Hofgarten," so you will enter from the street and walk to the middle to access the stairs to the apartment. Therefore, you will not hear any street noise, just the occasional, soothing sounds of life in the apartment block.
One final note: the apartment description says it's on the 3rd floor...but for Americans, this means it's on the 4th floor and there are 12 flights of stairs, no elevator. Great workout though. ;)
I hope to come back next year.
