Jay's apartment is great. The position is perfect and it allows to explore Madrid center really easily. I totally recommend Jay's place.
The apartment is nice and has everything you need, in addition the bathroom has been recently renovated.
Jay and Boba are very thoughtful, they even allowed me to check-in earlier with respect to the indicated time. The only thing a little bit off concerns the bed sheets/towels change, in fact the guests are not allowed to have direct access to these items, so changing them can be a little complicated depending on your schedule.
