ALLROUND RENTALS offers competitive rates and friendly service. They speak English and will help you with maps and tips and advice on where to go and what to avoid. I also recommend them because it’s easier to pick up and drop off at their place than in the center of town, where traffic and one-way streets can be frustrating for anyone not familiar with driving in Munich. Directions to their location: From the Hauptbahnhof take U1 or U2 to Sendlinger Tor, transfer to U3 (dir. Fürstenried), get off at Obersendling. From Marienplatz simply take U3 (dir. Fürstenried) to Obersendling. It´s an easy 3-minute walk from the Obersendling U-bahn stop to their office. From the  Obersendling stop: Come out of the train and look for the sign/direction Tölzer Strasse. Go left when you come out onto the street and right at the corner (150 meters). They are in the Boschetsrieder Str. 12, across the street from where you´ll come out to it (just a bit to the right).
