The home is in a wonderful location. That being said, we had a few issues. First, it was listed as a private home, when in actuality, you share an entrance to the home with the host, so there is a possibility of running into them at any time coming in or out of the apartment. Once inside your wing of the apartment, it is private, in that you have your own bedroom, bathroom and little sitting area.
There was construction going on while we were there, not Helena's fault but it sound does travel easily it seems from your bedroom. So if you are looking for a romantic get away, this may not be your top choice.
All that being said, Helena is a friendly host and if you want an unbeatable location at a decent price from which to see Madrid, this is your spot!! I recommend for single visitors or friends who want to be where the action is at a reasonable price.
