This is a large apartment in a great location. Tons of restaurants, cafes, and stores within a 5 minute walk, and most major sites in Sevilla are within short walking distance as well. The apartment was recently renovated and is generally in good working order.
Having said that, there are a few issues guests should be aware of:
1. The bedrooms face towards a large construction site where they start using loud equipment around 7:30 or 8:00 AM every weekday. It is so loud that you won't be able to sleep in even with earplugs, and the size of the construction site leads me to believe that it will be going on for another 1-2 years.
2. The double bed is very hard and narrow. Two reasonably skinny adults can fit there, but you will be bumping into each other all night long anytime you turn.
3. The air conditioning in the bedrooms works great, but the one in the living room doesn't work and gives the place the smell of a moldy sewer. I hope the owner can fix that.
4. The apartment is on the 2nd floor, or what would be called the 3rd floor in the U.S. There is an elevator, but it only goes to the 1st floor. If you have heavy suitcases, be prepared to carry them up a steep staircase between the ground floor and the first floor. This was clearly disclosed in the listing, but be aware of the 15-20 steep steps.
Would we stay here again? Yes, for the value, location, and recent renovation, but we would wait until the construction across the alley is done.
