We were 10 women, and Xperior's place was perfect for our needs. The biggest perk was that we had 4 bathrooms and two kitchens - important for 10 women :) Checkin was very easy and the hosts were extremely responsive. The beds were very comfortable, the bathrooms were clean and modern and the kitchens were well equipped. Also the location is fantastic - the canal is right near by, and there are lots of cafes, supermarkets and restaurants within walking distance. The subway is close too. One thing to note is that because its a basement apartment it is a bit dark. Also, there were corners of the apartment that had a faint smell of mildew. And while the rules say no smoking, there must have been guests who did not abide by this rule because in one apartment there was also a faint smell of smokiness. Overall these were very small issues and didn't bother us much. If I were to return again to Berlin in a large group I would want to stay in the same location.
