Uwe was a wonderful host -- very good with communications and also very flexible when we needed a later check-out. The location of the apartment was wonderful -- we could easily walk to all the key sites and it was also easy to get taxis. Being close to Arthur's seat and having the amazing view from the 4th floor was wonderful. (And it's true that the elevator works really well.)
The apartment was quite comfortable and we loved the kitchen set up. Also having a washer/dryer for clothing was very convenient.
The only things that surprised us was that the shower in the en-suite bathroom was the smallest we'd ever seen. It was hard to shower in it. Also, the bed is a double/full -- comfortable but small. The kitchen has really nice appliances but most of the furniture/wall art was pretty low-end. We've found this to be true of many Airbnb apartments -- they're furnished with quantity but often not quality. Not that that's Uwe's fault, just to set expectations. Overall we loved our time in Edinburgh and are grateful we found Uwe's place.
