Unfortunately, we were pretty disappointed with this tour. I WOULD NOT RECOMMEND TO ENGLISH TOURISTS.
The main issue being that we were not aware that the tour would be bilingual. In a large group of at least 20 others or more, we were the ONLY English speakers. It was awkward as the guide would spend a large amount of the tour explaining things in Spanish, and then quickly give the English translation.
It seemed obvious that we were not getting as much information as the Spanish group.
Additionally, we just felt awkward as we felt like we were holding the rest of the tour back as they had to wait for us to have everything explained again in English.
I also felt that our guide was not that informative, and I learned more about the Alhambra reading about it on Wikipedia after the tour.
Disappointed with Viator... I thought it would be a trusted way to book local tours. However, after this experience, I just don't know if I would book through them again.
Although when I scheduled our tour I was apprehensive that it would not be worth the price I paid, I was not disappointed. The guide was excellent, he was knowledgeable, easy to hear and understand and somewhat witty. We learned much in our tour, not only about the buildings and architecture, but much about the culture that produced this magnificent complex. I feel very happy I made this investment.
Our guide, Raphael, was easy to understand, knowledgeable, and patient. Raphael was able to switch back and forth between English and Spanish quickly and explained everything to our multi-lingual group with lots of stories, history and background. He did seem to go on a bit longer in his native Spanish than in English, so at times I envied the Spanish speakers the extra details they received, but I don't feel we Anglos got short shrift. We took the early morning tour that allowed us early access to the grounds when only a few tours were inside, before the crowds, and I thought it was well worth getting up early and climbing the hill in the dark.
La Alhambra is one of the don't-miss sights of Europe, and if not just for the impressive grounds and intact historic structures, then for the stunning views of the city of Granada and the surrounding countryside to be had from the site's walls.
The audio system worked well, though it was line-of-sight, and if we were at the back of the group as we wound through buildings with thick stone walls, we lost reception for brief interludes. I considered it an inducement to keep up.
We went in September of 2017, and the weather was perfect. Sunny, warm, dry, not too hot.
To get the most out of this tour you must be able to climb stairs, lots of stairs, and walk at a good pace. Sturdy shoes, at the least runners, would be a very good idea.
As many people helpfully pointed out on reviews I read before choosing this tour, THIS TOUR DOES NOT INCLUDE THE NAZRID / NASRID PALACE. You will need to book that separately. While the Night Visit to the Palace came highly recommended, we found the moody and romantic lighting was just dark and you couldn't actually see very much. Go in the day if you can.
I would recommend this tour to friends and family.
