We had a great stay at Beatriz.
The location was great, it was within walking distance to most if not all tourist sites in Seville. The apartment is clean and comfortable. Check in and check out procedures were straight forward. Beatriz was very kind to recommend restaurants and she even did our laundry for us. The only thing is note is the size of the bathroom. It is on the smaller size and might be difficult if you are bigger in size.
