Wonderful location to explore Seville from! Views of the cathedral and surrounding area are spectacular. We were in late May/early June, so the weather was also nice enough to allow us to sit out on the terrace in the evenings with a bottle of wine and in the morning with coffee while enjoying the views.
Upon arrival, we got detailed information on sights to see and recommended dining, bars, and entertainment which was very helpful, and we were able to see might more than we thought we would be able to. Since it was a penthouse apartment, it was also quiet at night to sleep.
Until you get used to the layout of the surrounding area, it can be a bit easy to get lost, so I'd suggest having gps on your phone to help navigate around! :)
