Our stay in Seville was very pleasant. The space is stylish and very clean. Comfortable beds and sitting area. The Beth room is spacious and the shower was hot, easy to use and very powerful. Just a note that there is no solid walls between bedrooms so you would have to feel very comfortable with the people you were staying with as noise does carry. It may not be appropriate with toddlers due to the staircase. Also, there is no real view from the property, you can open the downstairs blinds but it is straight onto a street and people can see in. But if you are just wanting a relatively central location for exploring the city then it is a very nice apartment.
All 4 of us had a very nice stay, it’s close to the town and communication with Nacho and Irene was superb.
