I could probably write an essay on why Hidemi's place is not only a great place/value, but why Hidemi is such a wonderful host as well. To clarify a bit, I actually stayed a lot longer than most people probably are--I was there for nearly a month while I was a visiting scholar at the Technical University of Munich. However, throughout the entire time I stayed with her, from the moment I got off the UBahn and until the very last day, Hidemi really went above and beyond to make sure I had an excellent stay and went out of her way to really make me feel welcome. Seriously, it felt like having a surrogate mom taking care of you...especially since being a visiting researcher is not the same as just being there for vacation.
Every morning I woke up and got a delicious, nutritious breakfast before heading off to the university. And when I got back, she always greeted me and would often ask if I'd like some snacks or tea, which were most welcome if I'd had a particularly stressful day. During weekends, she always had suggestions on local (or far) attractions to see, and I ended up going to a lot of places I probably wouldn't have if it weren't for her great recommendations (and excellent local tips). If I ever needed to figure out something, Hidemi was always willing to help.
The location is also excellent, as it's literally right outside the Hohenzollernplatz station, so the downtown areas are just a couple stops down, and it's easy to make connections to other lines via bus or just on foot. The directions were super clear and I did not get lost at all heading over from the airport. I really enjoyed walking around the neighborhood as well, just checking out the charming shops and quiet parks that are within 5-10min walking distance. The room I stayed in was spacious and perfect for a single traveller, and very clean with charming decor. The single bathroom is shared, so you should be mindful of how long you're gonna be using the shower/etc., but I rarely had any issues with that. If you need to do laundry or want to cook, Hidemi can definitely help you with that.
Overall, I cannot recommend Hidemi-san enough; I actually got a bit misty-eyed as I was getting ready to head out on my last day--waking up at a god-awful 3:50am to catch my 7am flight out of the airport, but despite the hour Hidemi was up and ready with a lunchbag for my trip, and saw me off even though the sky wasn't even light yet. I'll never forget this experience and her kindness and hospitality that made it so wonderful.
