Marta's apartment is super nice. It's got a stunning 6 balconies facing the street, so there is plenty of natural sunlight and beautiful views of Madrid's rooftops. The apartment is fully equipped with all you need to spend a holiday in Madrid. Clean sheets and towels, as well as all basic condiments and supplies for you not to worry. It's right in the hart of Madrid, under 15 minutes walking from the plaza del Sol, and for any further distances the metro (subway) is a 1 minute walk away which has easy access to and from the airport too. There is a supermarket right downstairs and another bigger one a block further up. I had to get a couple of days I nedded to get work done and it is important to say she has a very good and fast fiber optic internet connection, which came in very very handy.
All in all, the flat is located in a very lively neighborhood of Spain's capital and it is ideal to have a stroll around grab a bite, a coffee, a beer and people-watch in this truly wonderful city.
