Charles was a great and caring host, even if we didn't have the chance to meet him and/or his family personally. Nonetheless, check-in and check-out was very easy. Regarding the flat; it is beautifully located in the heart of picturesque Noting Hill, with lots of cafés and shops in the neighbourhood. The closest tube station is only a 10 min walk away, and provides fast and easy access to Oxford Circus (Central Line). The flat can accommodate up to 5 guests with 3 bedrooms and 2 bathrooms and a large kitchen is available, too (but, you should definitely go out and enjoy London's variety of restaurants). It was nicely decorated and the view from the balcony is great. Towels, soap, shampoo, dishes etc. are all provided, so rest assured and enjoy your time in London! In case that you're open minded, you might even make friends with the locals, as we did.
Long story short, thanks again for hosting us, Charles. We are looking forward to our next trip to London. Cheers!
