The hosts were out of town on business, so I didn't get to meet them, but check-in and check-out were simple and I had no problems during the stay. Communication was very timely before check-in as well.
The room was pretty large and comfortable, though the floors were a bit creaky which made it difficult to be quiet if I had to move around at night. The entire apartment is clean and well taken care of.
Location-wise, it is conveniently located just a short walk from the Pimlico underground station which provided easy access to the Victoria line and central London.
