We (two couples) enjoyed our stay here pre and post trip to Machu Picchu and the Sacred Valley. We appreciated that we could store our luggage between stays as we had items specific to the Galapagos trip we had just taken (plus the Amazon trip necessities our friends had in tow from their extension). We were given spacious, pretty rooms each time. Beds were comfortable and the bathrooms were spotless. The restaurant, though pricey, offered tasty food in a nice setting. The breakfasts were great. I found the service to be very helpful and thoughtful. My friend celebrated her birthday here and the staff were kind enough to make sure we had something special in her room. The hotel is conveniently located so we walked to the various sights in the historic center from here. We would certainly stay here again.
Do have a pisco sour (or two) at the bar called aptly named Pisco Sour Museum. We don't usually visit chain eateries on vacation but the Starbucks in the square is in a gorgeous building with a great balcony from which you can sip your coffee while overlooking the square and all its goings on.
