The apartment was very comfortable, quiet, immaculately clean, in a great location and with fast wifi. The reason for the 4 stars is that a few small things detracted from the experience. The main issue was the double bed, which was the smallest I have ever seen, with a terrible bouncy metal frame and mattress. Not possible for two normal adults to share, and made for very poor sleep, despite the room being plenty big enough for a real bed. I didn't like that there were cameras and sensors everywhere, makes me concerned about privacy. Also, no kettle, no bin in the bathroom, no kitchen basics (salt/pepper etc), these things are minor but are irritating and easily fixed, especially given the price.
