This unit is just as described, right in the heart of Madrid. It's centrally located so you can walk or ride the Metro very easily from this location. My sister and I shared the space and found it had much more space than we were expecting, with plenty of storage for our clothes.
I would highly recommend the local Free Walking Tour when you arrive to get an even better perspective of your surroundings.
Booking was easy, Fernando was very quick to respond and confirm our reservation. Check in/out was simple as well. I would highly recommend this unit to friends and family for future visits! Thanks!
