We stayed 10 days in the apartment while visiting our daughter. The apartment was as advertised. It is clean, comfortable and the neighborhood is quiet. There is a supermarket a few steps away from the apartment and a plethora of bakeries too. We had a lovely dinner one night at a Cuban restaurant called Al Son de Cuba (Calle General Lacy 11, Esquina Ancora). There is a 45 bus across the street or you can take the 3 subway line up the block. Atocha train station is very close- go inside to see the garden!
You will be close to all of the tourist attractions by foot or by public transportation. Recommend buying tickets on line to following attractions: Reina Sophia Museum, El Prado Museum, Royal Palace, Royal Botanical Gardens, Frieda Kahlo exhibit. Oh, and wear comfortable shoes because you will enjoy Madrid more if your feet don’t hurt!
