Lybi's apartment was just what I needed for a few days in London. A comfy bed, a good shower, a great kitchen space, a sofa to crash out on to watch the TV, and very reasonable broadband speed. Everything wa spotlessly clean. The space is used really well to make it feel homely.
Within a couple of minutes you are at the train/tube station, there are plenty of bars/restaurants/cafes to chose from, and the apartment is well insulated from the noise.
The communication from Lybi was great - I knew everything I needed well in advance.
