Beautiful, clean, updated place with a wonderful location! Oscar was very patient and helpful through the inconvenience of me locking myself out with the keys on the inside of the door. Since the keys were on the inside in the door, there was no other choice but for him to call a locksmith while I was out of the house with no phone data or battery to communicate easily. There is a big silver 4 on the door. This is important since the doors are not marked 4-1, 4-2, etc. The neighbor, Doña Marie, was also very helpful. Sometimes the streets can be confusing because they look the same, but my landmarks were across from Calle Toledo, across from Five Guys, and next to a store with an outside wrack selling clothing (mostly dresses). Very comfortable stay despite my own faults and mishaps! The location, updates, and modernization of the apartment cannot be beat since this is a historical area of Madrid.
