The hotel may get its name from overlooking the Imperial Palace gardens, but it is a palace in its own right. I was hesitant to stay here based on reviews that said it was a business hotel, but to me, it was far from it. Three of us shared an enormous room with a bathroom nearly as large to go with it, and a balcony with a stupendous view of the Imperial Palace gardens and the high rises of Tokyo beyond.
Admittedly, this was a splurge for a special birthday with two friends who were also celebrating this special birthday, and the Palace Hotel couldn't have made it more special for us, including sending up a platter of complimentary fruit and chocolates for our birthday and advising us on places to dine in Tokyo. If I were to return to Tokyo any other time, this is the place I would pick, although admittedly the Tokyo Station Hotel (where I also stayed and enjoyed) is probably more convenient to a train station.
We enjoyed a stellar cocktail in the upper lounge--so good that I asked for the recipe and still make the drink at home now.
Really, do yourself a favor and stay here if you can afford it. You won't regret it!
