Wow, what a find! The apartment is self-contained within a lovely gated community. I visited on work, and it was only 20 minutes and a cheap cab ride (using "Mr Pedro's" recommended firm!) to Heathrow. Easy to get to the Tube station and some nice restaurants nearby.
The apartment itself is great- plenty large enough for a couple, plus a kitchen which made sorting out breakfast a doddle. Comfy bed, quiet and nice powerful shower in the morning. I really wonder why hotels bother with these types of places available!
A big thumbs up to Ana! We'll be back.
