This is a pretty great place to stay if you want to be in the middle of the action in Seville. The apartment is comfortable and has everything you need for a great stay.
Do note that due to the apartments' location, there is some noise from the surrounding areas that can go fairly late into the night. Take that into consideration when booking and bring some ear plugs and/or a white noise generator.
Overall, though, this is a great place. The hosts are fantastic and were extremely quick to respond to any questions I had.
