Things about Sergio's place that made my life better: unbeatable location, super comfortable beds, great water pressure in the showers, three bathrooms, extremely spacious, tastefully decorated, very secure, helpful cleaning service, regular water delivery, and plenty of supplies like towels, toilet paper, and soap.
Sergio was very responsive and fulfilled all of my requests right away. He even provided me with a radio to help me with my Spanish studies. He is a very thoughtful and communicative host.
I had a great time at Sergio's and I would have stayed longer if I could have afforded it! It was really hard to say goodbye.
