Staying at Gerd's place was a delight. First of all, the host. Gerd is amazing! He was available before and during our stay, and really helped us get a better experience while staying in Munich. When we first arrived it was evening and I contacted him for a few minor things we needed in the apartment and for restaurants reservations. He answered us quickly and helped us with what he could remotely, and said he would take care of the things we needed when he came back to the house a bit later (which he did). He then recommended us on a few restaurants which we picked one of, and funnily enough we met him at that restaurant. His company was great whenever we had a chance to meet him (which unfortunately was not many times because of our trip schedule) and he also provided us with great suggestions of sightseeing in the city.
Now the house. It's a great place. The rooms were cosy, warm and clean. The tenants share the bottom and second floor bathroom (but since the house was fully booked, Gerd allowed us to use the bathroom on the top floor if need be, which i think is his personal bathrooms) and also share the kitchen area, which was fully equipped with everything you would need. There is also a backyard and there are washing machines and a drayer in the basements. The shared area makes it so you meet other people while staying in the house, which for us made for a more enjoyable stay since the other guests were nice. Everything in the house was well maintained and very nice, and it seems the house is in the style of an old Bavarian house which made for a more authentic experience.
The location is fine. It's not a walking distance from the city center, but the public transit gets you wherever you need to go easily. By the way, the Munich public transport payment system is very complicated, so as Gerd suggested we just bought a 3 day all zone ticket and avoided dealing with the complicated system, though I believe you can travel more cheaply if you have the patience to try and understand the payment system. We got to the city center, or anywhere in the middle of the city, in about 20-30 minutes in public transit if I remember correctly, which is quick enough the way we see it. In walking distance from the house there are supermarkets and restaurants (as I've mentioned) and we manged to get anything we needed easily and quickly.
All in all the experience was great, and I will definitely consider staying at Gerd's place again if I come back to Munich!
