This is a great option for a small group of people (2 to 4) given its location. It's a small but cozy apartment with great features. Very comfortable master bedroom. So, if you are looking for a place to crash after hanging out in Madrid, this is 100% recommended.
One important thing to keep in mind is that unless you make arrangements with the owner in advance and pay an additional fee, there is no assigned parking space available. You will have to park on the street at your own risk. But, if you are moving in Madrid using Public Transportation, this apartment is just what you need.
