We had a lovely stay at this apartment in Madrid. It is just as described. Very modern decor and equipped with AC to keep you cool during the summer. Our check in was smooth and we had no issues with the electric keys. However, we didn’t know the reception was closed on the day we checked out after we were told we could store our bags there before our train. We had to wait on someone coming to let us store our bags. It was a clean, beautiful and well located place to stay but this could have been advertised in advance.
