We were travelling with our godsons (aged 14 and 17) and the apartment was just right for us. Both boys had their own bedroom and shared a bath and my husband and I had our bedroom and our own bath.
The apartment was very clean, the rooms big enough and the balcony a great bonus for us. We enjoyed to stay up there before and after dinner and watch the planes on their approach to heathrow.
There is a supermarket, café's , pubs and a tube station near the apartment. Communication with Sole, check-in and check out were very easy.
