The good things about this hotel: The room was clean. The staff were friendly. I slept pretty well. It's only a 45-minute walk through winding residential roads to get to Twickenham Stadium (that's about the same amount of time you'd wait for the shuttle bus when leaving the stadium anyway) and a 15-minute walk right down the street to a Tube station.
Other than that, I was disappointed in this hotel from start to finish:
* I booked through the hotel's website, entering all requested information (including credit card), and received a confirmation email of a successful booking. I thought I was good to go. But the next morning I got an email referencing the wrong hotel name ("Park Grand London Hyde Park" instead of "Park Grand London Heathrow") in which they threatened: "Please be advised that the credit card details you have provided for this reservation are invalid. We request to provide us with a valid card’s details within the next 24 hours to keep your reservation active or we would have to release the room." So, I scrambled to make an international call to sort things out and to verify that they hadn't switched me to a different Park Grand property (fortunately they hadn't) or cancelled the reservation. According to the operator I called, they hadn't saved the credit card number that I entered while booking; it was simply blank in their records.
* I booked the "Rugby World Cup Fever 1" package, six weeks in advance of my stay, and at higher expense than the best-available rate. The package was supposed to include a "Complimentary Rugby World Cup Sponge Ball" and "One Complimentary Drink per person on arrival." I specifically picked this hotel over other options because I was looking forward to the sponge ball as a souvenir of my trip to watch the World Cup. But when I arrived there were no sponge balls available. (And no complimentary drink was offered during check-in.) To their credit, when I inquired later in the evening about the sponge ball they apologized and sent a small bottle of wine to my room. But, at the risk of sounding like a whiny 6-year-old, I would much have rather received the thing that I'd specifically booked in advance through their website.
* The towels in the room had frayed edges. The rainfall shower head was nice but the nozzles needed cleaning, so the water jetted out in multiple directions instead of coming straight down. One of the two exterior windows on our room was cracked across the entire horizontal length of the window. (It was the outside pane of a multi-paned window, so there was at least no risk of us getting cut.) The hotel is right underneath one of the landing flight paths to Heathrow, so my roommate was woken up several times (though I was not).
* The breakfast buffet had reasonable selection but ordinary taste, and I was disappointed that there are fairly steep extra charges for the "a la carte" items on their breakfast menu such as french toast or made-to-order eggs with toast.
* The hotel does not offer shuttle service to either the Tube or to Heathrow. It took us 35 minutes to get from the hotel to the the Terminal 3/4/5 station (via the Hounslow East station) -- that's reasonable time, but not nearly as fast as I would expect given the word "Heathrow" in the hotel's name.
None of these problems are terrible, and to reiterate I did sleep pretty well. But given the problems plus the price for the room (higher than usual due to the rugby game that night) I feel I didn't get good value for the money, so I wouldn't book again. less
