Great location, great flat and we were happy to find a bottle of wine waiting for us! We were allowed to check in early which was super helpful. We had to check out by 11 (as advertised) but found it easy to leave luggage in lockers nearby (Rossío). There's no shower gel or shampoo in the flat and also not much in the kitchen, so you may want to bring or buy some basics. Otherwise we can't fault it at all and loved our stay. We are planning to return soon, so can definitely recommend it!
