I would highly recommend anyone to stay at El Viso Smart in Madrid. The apartment is very charming and has all the utilities needed for a week's stay including a complete kitchen and a washing machine. It is accessible to various modes of transport and is very near a grocery too! The best part is, our hosts Antonio and Javier were helpful in ensuring that our stay would be as comfortable as possible. If you're heading out to Madrid, El Viso Smart would definitely be best place to stay in.
