We really enjoyed our stay at the apartment - it was spacious and comfortable and filled with all the amenities we required. The location is also great with lots of bars and restaurants in close proximity. Carmen was really good at communicating both prior and during our stay.
The only issue we had was a foul smell coming from inside the apartment that continued throughout our stay. This meant we probably spent less time at the apartment than we'd have liked. We told Carmen about this during our stay and, although she was unable to fix it whilst we were there, she assured us it would be looked into once we'd left.
We would recommend Carmen's apartment to others who are looking to spend some time exploring Seville.
