There is a cat which is not mentioned in the listing description. If you are allergic to cats this can be a major problem.
I expected a bit more out of this for it being a plus listing, but it seemed no better than previous stays I had had. The bed was pretty uncomfortable as was the single pillow we were each given (I feel like two per person should be standard). There were a few cleanliness issues on the toilet and kitchen too. On the positive side, siwen was very communicative and made sure to give us good tube directions to and from the train station
