This appartmanet is very nice and cosy. Feels like in the old English Castle: there is a fire place (not in use), round table, big chairs... The bed is new and very comfortable. Bathroom with a real bath and good shower, small kitchenette stuffed with everything you need.
What I liked is that it's on the 4th floor, with big windows, so it's warm and light.
One of the highlights is the collection of books: there are some famous English novels, books about London, maps, even a book about birds, that you can meet in St James Park in 5 minutes walk from the house.
The location is just perfect for exploring London: you can walk to main attractions, Underground is actually in a couple minutes walking, also Victoria station is very close.
Thank you very much, Piers!
