Ralph's place was great!
Location was only 5 minutes off of Kolumbusplatz station, which will is only 3 stops from Munich's central station - very convenient! Only a 25 minute walk to the Oktoberfest grounds, which we walked three nights in a row. It's far enough from all the hustle and bustle, so you feel like you're in an actual neighborhood.
Keep in mind that the place is on the fifth floor - so your legs will be feeling that! Pack lightly.
Restaurant downstairs has great burgers - just a heads up!
Place was very clean and had everything you need. Dishes, fridge, washer. Wish there was a bigger sitting area, but that's nothing major. Would definitely stay here again!
