The flat is exactly like in the pictures, very well located just 2 min walk from Ostbanhof where you can find buses, metro and trains going everywhere in Munich. The neighbourhood is also really nice with pretty much everything you need close by.
It is a quiet flat so very good to sleep at night and Katharina left it very clean for us, with towels included. Wifi connection is good, we were two people doing home office and there was no problem. The communication with her went smoothly, and we would definitely stay there again.
In my opinion it is an ideal place for one or two people to stay, more than that I think it would be small. We were cooking while we were there, so this is also possible. But bear in mind that, as you can see in the pictures, the kitchen space is limited. There are bakeries, supermarkets and restaurants close by so it was not a problem at all.
Overall I recommend it !
