I highly recommend staying here. The apartment is sparkling clean, very modern, and comfortable. The couch in the living room is extremely comfortable. Location is amazing with easy access to the metro and within walking distance of many Madrid attractions. The only potential negative I could foresee for someone is the very steep, narrow spiral staircase up to the bedroom/bathroom. If you have mobility issues it may be difficult to climb or descend. I would happily stay here again next time I’m in Madrid!
