Of all the cities I've traveled in, the location of this place in historic Madrid may be the best. We were literally within walking distance to almost everything. It was beautiful. The building was historic and gorgeous, while the unit itself was stunningly modern and clean. It was quite the contrast to look out the French window and see this historic street below from inside. Other reviews mention the AC, but we were more worried about heating, since we were here in February, and this place heated up nicely. Quiet inside, with a vibrant street full of pedestrians just around the corner, I loved how this place felt.
