Our stay at Juan Carlos's was incredible. Check in was very easy despite the fact that the hosts were travelling, as the communication was very clear and they were readily accessible. The space is to die for, and too beautiful for words. We felt like royalty. There are so many thoughtful touches to add to the space's natural charm. It is also located centrally, with many markets, restaurants, and shops around. The Alcazar and Cathedral are a very short walk away, and the Plaza de España was about 20 minutes away, a beautiful walk through a historic district.
Our only complaint was that, as this was a shared space, we were woken up a few times by our neighbors in the next room being incredibly loud at various hours in the middle of the night -- 3 am - 5 am. This is of course no fault of the host's, but it is good to note that noise-consciousness is good if you stay in this home. But the shared bathroom traffic was not bad at all.
