Piet's Dream city flat is GREAT! I believe I lucked out completely by choosing this apt. It's right in the heart of "happening" Munich - you are in the middle of the museum district and the university district. There are tons of restaurants at every price range right outside your door. You are minutes away from the English Gardens and the center of town is either a pleasant 20 minute walk away or reachable by public transportation literally a 2 minute walk away (bus stop).
The apartment is delightful and has absolutely everything you need, from a hairdryer to butter in the fridge! When I arrived I stopped in a bakery to pick up a "welcome to Munich pretzel" (my words) but forgot to ask for it to be buttered. To my surprise I found butter in the fridge. Thank you Piet! Everything works, the place is super clean and Frau Schmidt, who gives you the key and shows you around if Piet is not there to greet you, is very friendly.
The apt is on the fifth floor without a lift. This is a bit of a shock when you arrive - at least it was for me. But you get used to it. As Frau Schmidt said, just take it slow and easy. And I did. I also saw it as a way to burn off some of the calories from that yummy Bavarian food.
I would recommend Piet's Dream city flat without hesitation. He is a perfect host, even when he's not in town. He helped me set up my wifi connection over the phone and we had a few very nice conversations. Sorry we never met in person!
