If you are looking for a conveniently located flat (3-minute walk from Paddington), this is a great choice. It is dead easy to get to from Heathrow via the Express or Elizabeth Line. Like most Mews in London, the street is really cute and private. Also, we were able to check in a few hours early which was super helpful! It was great having laundry in the flat. It took hours and hours to dry, but you can just leave it drying when you are out and about, so it's okay. The kitchen has anything you need in terms of kitchenware.
However, there are a few issues with the flat. First, the stairs up to the second level are VERY narrow. There is hardly enough room to step on some of them, and I nearly fell a few times (I don't have any mobility issues; the stairs really are just super narrow). Also, the handrail is not securely attached to the wall, so it wobbles when you try to hold it going up and down. The shower is tiny and the room is hardly any bigger than the shower itself, but we expected that in central London.
There are also some inconsistencies in the listing that you should know about. It says checkout is at 11, but the email we received before checking out said we needed to be out by 10. The listing says there is a king bed, but it is barely a double. The listing says there is a "spacious lounge leading to a balcony with seating," but the lounge is not spacious, and there is no balcony. The listing said there would be soap, and there was not.The listing claims that the kitchen has modern appliances and a modern finish, but the oven/hob is quite old, and the kitchen is quite dated.
So, in sum, this is a really great location, and the host is very accommodating and helpful. The listing has some inaccuracies, but overall I think the place is a good value based on where it is.
