The checkin and overall communication with the company that takes care of the flat was great. They do really respond in very short time to any questions you might have. Thanks for the extention on checkinh out - really appreciated. As for the apartment we had a mixed feeling: a good size, in a great neighbourhood, nicely furnished and we'll equipped. However, second floor on VERY narrow stairs - difficult with luggage; VERY squeaky floors- you literally hear every step and conversation of your neighbours ; second bedroom good for small kids, not grown-up ones; the heating in the second bathroom didn't work - being there in the coldest week that London saw in the last decade we just couldn't use that bathroom; too bad as it could have been much more comfortable. I could have oversee anything else, but the noise of the floors.
