I was more than fortunate to have found la senora Margarita's extraordinary apartment. More than being well-maintained and tastefully decorated, her loft-type unit is an architectural delight. The photographs provide a description but doesn't fully show how wonderful it is.
While it is not very close to the center, it is conveniently located sufficiently close to the Metro. Moreover, the quiet, safe and easeful neighborhood brims with restaurants and small shops of many kinds.
Margarita and Rafael were considerate, delightful, and exceedingly helpful. Altogether, these things contributed to a very nice stay in Madrid. I certainly would stay here again!
