After staying at two different hotels in Lima, with less than expected results, I gave the Piru Wasi a try even though there was only one review on the place and my taxi driver trying to steer me away from it. I am really glad I didn't listen.
You CAN'T judge it by what you see from the street, although I am not saying it looks bad from the street, it's just that there isn't much to see. Once you enter it's another story. The entire staff is incredibly welcoming, kind, and helpful. They go above and beyond to make your stay as pleasant as possible. The courtyard where you eat your breakfast is clean and very nice and the rooms seem very new and are beautiful. Had a problem with the TV in my room and they immediately switched me to another with a balcony overlooking the street.
I really loved my stay here and if I return to Arequipa I won't even think about staying anywhere else.
