The apartment is very much as described, and Carmen's communication and help with any detail we inquired about was fantastic. It's a lovely, spacious (for London), homey apartment, with high quality fit and finish. Of particular importance for us, the mattresses and linens are of very good quality.
I can't add anything to the great descriptions in the listing and other reviews, but I will emphasize the incredible convenience of having the train station just two minutes away. In addition, there are three really good restaurants in the same two-minute radius (Mildreds and Cafe Route were our favorites), which is most welcome when setting out for, and arriving back from, a day of traipsing around the city.
