I know Berlin very well as I’ve lived there 12 years so I knew exactly where it’s located. The area itself is not particularly nice but the neighboring lychnerstr. And Kastanienallee are, as well as helmutplatz and kollwitzplatz. The house is exactly as depicted. The only think missing IMO is a bathtub. Beds were comfy, plenty of towels to choose from, all the amenities you need in the kitchen including dish washer and washing machine. Check in and out was easy and the house was spotless. Internet was fast and working. Nothing to complain about (ok maybe for kids a bathtub would be nice :)
