We really enjoyed our trip to Sevilla, and our stay in the apartment. The location was perfect, and the place itself was comfortable (great beds). The kitchen had all of the amenities we needed to make some of our own meals, and there were several markets within a few minutes walk. While the streets are super narrow, we were still able to get taxis to pick up and drop off at the apartment; we didn't have as much luck w/ Uber. Many of the top destinations are within a short walk, as well as several shopping areas.
Our only negative points would be the lack of hot water in the showers (we figured out you need to keep the hot water running in the kitchen to insure supply to the showers), broken locks on some of the sliding glass doors (this was repaired quickly) and the delay in response to text messages. We were only able to receive responses after calling.
We would still recommend this apartment to others, and would stay there again ourselves.
