Very good. i make reservation from website. they want deposit for reservation.

We stayed several nights here after visiting Machu Picchu. The location is great--on one of the old cobblestone lanes overlooking the Ollantaytambo ruins. The hostal is quite charming and pretty. Our room was simple but comfortable. The owners are very friendly and accommodating. A good buffet breakfast is served at the adjacent restaurant. All in all it's a fine place to stay in this very interesting town.

Hostel Iskay was one of the best parts about our stay in the Sacred Valley. Our little suite was comfortable and clean. The view of the ruins from our window made it special. The location on the tiny cobblestone street was very quite and serene. The service was excellent! Lluc took care of our every need. Plenty of hot water in our private bath, the bed and bedding were wonderful.

Comfortable rooms, yummy breakfast, and hot water. These things alone would make this place a good find in the sacred valley. However, the attention to detail and level of service found here make it truly outstanding.
The first thing you see upon arrival is a large container of free mineral water, with a request for guests to refill bottles in order to help with trash levels in the rivers. Very progressive for Peru! You are then shown the hot tea and coca station, surrounded by fresh herbs from the garden. There is a kitchen for guest use, a dining/living area, a pretty garden and patio, and lots of useful information about the area. The rooms and common areas are spotless.
The Spanish expat owner Lluc was awesome. We were interested in self-guided trekking, and he happily gave us suggestions and useful information without trying to sell us a tour. He has maintained the homey feel of a family-run hostal while giving guests the space and service level of a hotel. When we returned to Ollanta after several days elsewhere, Lluc smiled at us and said "welcome home!". Indeed, that's what it felt like.

One possible consideration for high season travelers- apparently camping is allowed on the restaurant lawn directly below the hostal, and I could imagine potential noise problems at times. We did not experience this. Also, this review is from the perspective of a budget traveler. If you are expecting the Marriott, you may be disappointed. Go stay in Urubamba.
