The pros:
* Location. Within a 1 minute walk, you can find an ATM, Starbucks, McDonald's, Burger King, Opera Pizza, Café & Tapas, Santander Río bank, metro station. 5 minute walk, and you get into El Corte Ingles, FNAC, etc.
The cons:
* As of November 2018, the contiguous building is in construction. It will be many long months until it's finished. So expect continuous, horribly loud drilling, hammering, demolishing noises, and workers yelling at each other from 7 to 5 on working days.
* We spent 4 out of 16 days in the apartment *without hot water*, because of a malfunction in the electrical installation. 2 days after reported, a technician come into place, failed to solve the issue and indicated "the whole building has been refactored just to rent, so installations are all flaky".
So this means, no hot shower. Host refunded one night of the stay for the inconvenience. We spent twice as much in a small hotel just to use the shower.
Horrible experience.
