I visited with my wife and 2 kids. The space is just perfect with 2 bedrooms and separate living space and kitchen. The best thing is the location....right next to Green Park station and in a very posh locality. We visited during the hottest days in London ever (!) so the air conditioning came in handy. Just be aware that you will have to carry your luggage up three stories with narrow stairs......which I guess is common in London city limits. Overall a wonderful stay and would love to stay again
