I stayed with Vilma and her husband for four weeks while relocating to London from Australia. Their house is in a fantastic location on the edge of Battersea Park (literally one minute walk to the park). The street is quiet and residential, but only a 5-10 minute walk across the bridge to the hustle and bustle of the King's Road in Chelsea with its array of shops and restaurants.
The house is spotlessly clean, and the room is a cosy double on the top floor with a bed, desk, and plenty of wardrobe and shelf space to unpack. Breakfast (toast and spreads or cereal) is provided every day, along with fresh fruit and tea and coffee. The room is cleaned and the bed linen changed weekly.
Vilma and Anthony are really fantastic hosts -- friendly and helpful with everything you need, but also respectful of your privacy. It felt like having my mum looking after me -- and I mean that in the best possible way!
If I had to pick a downside I would say that it's a little far (around 20 minutes walk) to the nearest tube station, but there are plenty of buses which will take you there more quickly. It's also worth pointing out that the room is not en-suite, but this was not in any way a problem and makes the room a bargain given the central location.
This was my first ever stay with Airbnb and I couldn't be happier. I would gladly have stayed longer if the room wasn't already booked!
