A very clean and nicely decorated apartment with lots of convenient items provided for a long stay. An excellent location close to all the good areas of Seville. The reasoning I'm giving 4 stars and not 5 is that there was a slightly unpleasant smell coming from the drains in the main bathroom which could often be smelt in the living area too. I told Numa about this and they said there wasn't anything they could do to fix it.
Something to be aware of (although it's not necessarily a problem) - there isn't really much natural light in the apartment because it's an interior room on the ground floor. If you're planning to stay for a long period and work in there day to day, that could get a little depressing, but fortunately there's a lovely roof terrace with chairs and tables that I often worked on.
Overall I had a great stay and I was content there but I would have preferred it without the smell.
