Rubens appartment is a great option for a Madrid visit.We love to walk and no place was more than a 25 minute walk.We did not use public transport or taxis during our 5 days,except from the airport.We even walked walked with our roller bags to the ATOCHA station.
The apartment is small but fine for 2 people.It is very quiet,no street sounds.
There are numerous bars and taverna's nearby.If you like Indian food there are several restaurants nearby.Ruben is very prompt in communicating.He was waiting for us at the apartment.Highly recommended.
