This place is amazing. Our taxi driver told us it was located in the richest part of Madrid and called it the "Golden Mine". The apartment is on the 6th floor and has a great view of Calle Velazquez. We were a group of 7 and we all felt we had plenty of room and didn't feel cramped at all. It's a very modern, clean, and comfortable apartment. Thank you Juan & Marina, my family and I had a great time! Would definitely recommend.
