Rosi is an absolute love and her place is wonderful. I found her building very easy and it is well situated. The building is secure and has a concierge during the week days. She greeted me with a hug and made me fee immediately home.
The place is vey homey. The room is very comfortable. Plenty of space, a desk, lots of storage. The bed was outfitted perfectly with plenty of pillows! Rosi has a map and recommendations ready for you. She had a fan ready due to the heat (much appreciated)!
Would highly recommend while you're stay in Madrid.
