Kristian was lovely and waited for us to arrive to give us the key (then went to work). Gave us lots of tips and mapped out places to see. The place is very clean and comfortable, with a full decked put logged. Location is very central and easy to get to, literally 2 mins away from the metro station, and if you're coming from Madrid on the train (Like we did) the apartment is only 3 stops away from the train station.
Thanks for your hospitality Kristian :)
