Antonio is a great communicator. He was kind, available and answered my questions promptly.
The apartment is located outside of the city center, which was one reason I preferred it, as I wanted a more residential experience. It was an easy and quick 10-minute metro ride to the center, which was much more convenient than I had expected.
Also, the apartment is just as it looks in the photos, and has a lot of light. There's also a small balcony, which is lovely. There were a couple of small things that needed attention, (e.g. the overhead light went out in the kitchen) and Antonio took care of it immediately.
A couple of things that would have made my stay even better is that I have a small frame and I could feel what felt like springs in the mattress beneath me (but it may have been the mattress itself, as it sits on a spring platform) making the bed somewhat uncomfortable.
Just a note: be careful when using the hot water, as it's set to a high temperature and could be scalding. I set the faucets in the kitchen, bathroom and shower to the half-way mark, and it was a perfect temperature.
