There’s no longer a washing machine (to the best of my knowledge). The house manual directs guests to a nearby launderette which is actually very good, especially for very large loads.
Apart from that the space is very much as shown. Entry is from the southern side, parallel to a busy street (although securely separated), but closing the door substantially reduces road noise as the place is double glazed throughout. The opposite wall is mostly glass, gets lots of sunshine and has a pleasant view of the back lawn.
There are two locked doors, one to the garage, and one to what is presumably a storage space. A third door leads to a spacious bathroom and toilet. There are fittings in the bathroom for a washing machine.
Cleanliness is very good (higher than average).
The WiFi is good, able to support video streams and Zoom-like conference calls.
Unless using the garage the family are rarely ever audible (the main house is very large and I think they must live mostly at the far end).
