Max is probably the friendliest local we met in Munich. You can tell he wants you to have a great stay at his place and in Munich. And generally speaking, we did.
The unit itself is very clean and conveniently located near subways, buses, restaurants in a non-touristy area. The only downside was that the room was advertised to accommodate 3 people, but I really don't think you can fit more than 2 people in the room. 3 was tight for us and we're small-framed women. I can't imagine 3 men staying comfortably in the room. I'd stay at Max's home again if I were coming with only 1 other guest.
