Great appartment in the heart of Sevilla. Clean and spacious, with a fully equipped kitchen. Two nice bedrooms and one large living room. Beautiful roof terrace (though shared with another party; you cannot access it directly from the apt). Fast and easy wireless. Javier was very forthcoming (thanks for the bottle of wine!) and waited for our arrival from the airport (the apt is a ten-minute-walk from the final airport bus station). Extremely responsive, too. For young parents: You can easily leave your babystroller downstairs in the hallway (it's locked) and just walk up one flight of stairs.
Put simply: We will gladly come again.
Very nitpicky drawback: The apartment is not well soundproofed so you can hear the people above and in the hallway walking around.
