OMG What a location! Carolina's apartment was perfectly located right across from El Retiro park which was perfect for a morning run, and to spend hours walking around the park, and taking my daughter to the playgrounds. The apartment was quiet, very well equipped and we had a very good night sleep on the three nights we spent there. Carolina was most helpful when we had questions, and went above and beyond to quickly mail something I had left behind after checkout. We'll definitely be back every time we return to Madrid. Gracias!
