The apartment was even better then the pictures featured on airbnb. We were 3 adults, a toddler and a baby and it didn't felt small at all.
The position is absolutely amazing: The Big Ben, Downing Street, Westminster Abbey, Trafalgar square, Piccadilly, Regent Street, Oxford Street, Covent Garden, Buckingham Palace...everyone of them within a walking distance so we never used the tube.
Tommaso was a great host, very helpful and concerned with our needs. The apartment was clean and tidy, beautifully furnished.
We had a great time and we'de love to stay there again in the future.
