We were in Seville for 3days an found Diego's apartment very clean and spacious. It was simple to get to from the train station and very close to the circular bus stop so it was simple to find. Diego met us there and gave us a bus card to use for our stay. We found that we didn't really need it as it was only a 15 minute walk into the centre of the city.
The definite highlight of this apartment was the view of the cathedral from the balcony! Each night we watched the sunset over the cathedral and the sunrise each morning. It was lovely!
There is also a supermarket conveniently located opposite, which we found very handy.
I would recommend this apartment if planning a trip to Seville!
