The good: the apartment was nice, very clean, super convenient location close to everything, nice outdoor space, easy check-in, and the hosts had great communication including offering lots of information about Seville and suggestions for things to do. The unit is on the top two floors of a four-floor building with the bedroom/outdoor space on the top floor, and the living room/kitchen downstairs. There is an elevator if you have heavy luggage, though we mainly used the stairs.
The not-so-good: our only complaint was that the place is not actually a two-bedroom. It could be a great one-bedroom apartment, but the hosts have put a bed in the living room and labeled it a two-bedroom when it's really something different (a one-bedroom with a bed in the living room). This wasn't clear to us from the posting (though maybe we should have read it more carefully?), and we would not have booked had we known as we would have preferred a real two-bedroom.
