Great location! We stayed 2 nights with 2 kids and it was literally steps from Madrid City Tour bus stop, walkable to everything and Alfonso was so kind. The apartment is really clean, stylish and quieter than expected for major road - but it is 6th floor so that helps. The AC worked great! Note - if you have bad legs it is a steep 6 flights of stairs up and down with luggage. We did fine, but it is something to consider for sure. Very safe feeling and comfortable. We highly recommend it.
