We loved the flat! It was very clean and looked great like you can see it on the pictures. Also, the location was perfect. You could reach all the famous sights and districts by short walking (Plaza de mayor 10 min, El rastro fleawmarket 2 min and so on). The only fact we didn't liked that much was that the flat got cold fastly because the windows weren't that thick (even though there was a heater that worked good). But this is not a reason not to HIGHLY RECOMMEND it! The communication with dan was easy and uncomplicated and his sister gave us a fast and nice introduction to the flat.
Thanks dan!
