Peter takes a genuine interest in his guests and is very accommodating/helpful.
The location of the apartment is great for being within walking distance to the Marienplatz and it's a safe area (we were two female friends on this reservation).
Also convenient to the street car stop which goes to the Marienplatz and gets you close to the Oktoberfest location :)
If you are coming by car, pad some time before meeting with Peter to check in, so that you can find parking on the street. Have up to 6 Euros in coins for parking; paper money not accepted in the parking machines (6 Euros for 24 hours).
