I spent a little over a week at this place and was pretty happy with it.
In my search, I was looking for a fairly central location in Munich that also had a washer/dryer and for some reason I had limited options available when I was searching. I picked Robert & Hannah's place even though there were not many reviews as I noticed that this was the place where they actually live themselves and rent out while they're traveling. So I knew there wasn't much risk of booking a place that was purely an afterthought for a side-hustle.
The place is in a pretty central location - the subway is a 5-8 minute walk away, and you can reach the central train station in a few stops. The neighborhood is pretty quiet but there's still cafes/supermarkets/restaurants all in walking distance.
I reached the apartment late in the evening when it was dark, so I got confused on where to find the lockbox despite the instructions. And my European SIM had expired the day before, and I tempted the fates by arriving without an internet connection. If someone else faces a similar situation, there's an open WIFI connection called 'vodafone ' that you can make use of for 30 minutes near the building.
I got almost instant answers from Robert/Hannah when I messaged them for clarifications, along with clear pics. The lockbox is a mechanical one with a rotary combination lock near the ground on the metal gate. And I had been fiddling with the neighbours' electronic security keypad all the while.
In the apartment, you have the living room, the guest bedroom and the kitchen available aside from a nice big balcony which would be nice in a warmer season.
The living room is pretty nice and I liked the official-like work table there. It felt like I was getting my work done in an office space. The only downside is that after dark, there's not much privacy - the curtains cover the window-wall only part way, and they're also transparent. Some people may like that so it's definitely subjective.
The wifi was perfectly reliable and I was able to attend my meetings without hassle.
The kitchen is perfectly equipped with everything if you want to cook yourself.
The guest bedroom was sufficient for the duration of my stay. The pics didn't suggest it but the bed is a sofa-bed. It's good enough for one person (or two huddled people) and I was able to sleep alright. If you're on the taller side, your feet may go past the length of the bed. There was a desk in the bedroom which I used to put my clothes and stuff on as there isn't an unused place for it otherwise.
All the questions that I had were promptly answered by the hosts.
All in all, it was a good stay for a week and I'd recommended it.
