Incredible view, big apartment, very central location (up a hill). It's easy to get to from the airport via the metro.
One thing to note, if you arrive outside of check in, you're required to pay an additional €20 cash on arrival. I didn't mind this per se, but I would have liked to know before I booked ("The check in is between 16:00 and 21:00 by appointment"). Oh, and bring earplugs – as with a lot of these buildings with wooden floors you'll hear everything the neighbours do.
Would stay again :)
