I booked the hotel for myself and my son via booking.com, and this was the cheapest-per-day and still reasonably central option. Being close to the tube was important, long walks are a sure way to sour the day if you travel with kids. Get an oyster card for yourself, and preorder a zip photo card for the kids to make it easier to travel, you can pick it up at the airport or locations in the city.
There is absolutely no problem spending a lot of money on "extras" at this hotel if you want to, but if you want to keep the price down, you ignore the hotel options and go for breakfast in the surrounding area (there is fast food and at least two "full english" options, as well as two grocery stores), and get a prepaid data card instead of the hotel internet. There are vending machines at Heathrow selling refillable data sim cards.
In general, we don't use "services" at the hotels we stay at, so I'm actually happy that they charge extra for it, and keep the per night price lower.
Our room had a heater/air conditioner, which solved the problem with drafty single-pane windows.More
