We (couple with 3yo kid) felt very lucky staying a few weeks at Fernando's place at the beginning of our long-term permanence in Madrid. The apartment is extremely comfortable and cozy; space, light and views do not lack. It is much better than one would guess from the pictures actually!
The location is ideal, just in one of the most livable streets of the city for our family - tranquil, yet lively, well connected and superbly serviced.
And Fernando is a great host, friendly and helpful.
We definitely recommend it and would return without any hesitation.
