What a wonderful place, right in the heart of bustling Madrid. The service and communication was excellent. The division between this apartment and the next is quite thin, so if you are unlucky with your neighbour you could be disturbed. However, the apartment itself, despite its location, isn't noisy. It is very small so ideal for a solo traveller. I was there on a working holiday, so the dedicated work space was excellent. The rare-for-Madrid outside space made the flat feel much larger and more open. Highly recommended
