Super apartment, small but efficient and very well equipped (plenty of towels, toilet paper, shower gel, coffee, sugar, you name it). And all equipment worked well. Also great location, in the centre of one of the liveliest neighbourhoods with a wide choice of bars, restaurants and shops at your doorstep, yet the apartment itself was surprisingly quiet. Brought my earplugs, but didn't need them. I like to explore new locations each time I visit Madrid, but for this apartment I would readily make an exception!
