Diana was an excellent host. Although we didn't meet her she kept us well informed and the person who met us at the apartment rang her so that we could speak to her on arrival too. She was very accommodating and helpful.
The apartment is ideally situated in a great area of London. There are lots of pubs, independent cafes and restaurants around. We can especially recommend the Moreish Cafe directly below the apartment for breakfast - they offer 10% off to "residents". The toasted banana bread and almond porridge is to die for! There is also a Waitrose just a 2 minute walk away and the apartment is well equipped enough to cook and eat a proper meal, with a large dining table and plenty of comfy seating.
We were 2 adults and one 16 year old, who slept on the sofa and said it was very comfy. I was a little concerned about the size of the bed as we are used to a super kingsize but it was fine and extremely comfortable.
The windows on two sides make it a really airy and light place to be. We were there in the middle of summer so needed to have the windows open at all times. Inevitably this meant noise, you can't be in such a great area without noise, so ear plugs are advisable. We live in the middle of nowhere so actually the buzz of a city was part of the appeal for us.
We travelled all over London on the "Boris" Barclays bikes. There were 2 stands very close to the apartment and at £2 a day for limitless 30 minute journeys it was a very convenient and cheap way to get around.
If you want a city break that is convenient to everything and surrounded by "real" independent shops and cafes then this apartment is definitely highly recommended.
