Apartment is conveniently located on Chiswick High Road with self-check in. The self-check is something to be wary of - the box holding the keys is attached to fence a few blocks away and the box itself is located under a pile of muddy dead leaves. If you are checking in on a day with wet weather please bring a pair of gloves with you to access the box.
I personally had a fiasco with the self check in as I had been provided with inaccurate information regarding the code to the lockbox. Once that was sorted and I finally got access there were no keys in the lockbox. The managing agent did courier me a second set of keys, but that took nearly 2 hours.
When I finally got into the apartment it was a mess. It had not been cleaned or serviced. The bed linens were old and used, there were no clean towels, the kitchen was dirty and the apartment looked disheveled. The cleaner came while I was there and did her best, but it was evident she was uncomfortable working with a guest inside, and I was uncomfortable as I felt like I was in her way.
Layout and size of apartment is fine for one person. It is well stocked if you need to cook. The hallways and stairs accessing the apartment are narrow - please bear that in mind with your luggage. The hallways are carpeted and my rolling suitcase did not transverse the carpet well. The carpeting is rather thick.
Should you have a problem of any sort and need to contact their managing agent please speak only with Richard. He was the only one who was helpful with the myriad problems that I had - only the key ones highlighted in this note.
