Rosa & Oscar’s apartment could not be more perfectly located. It was a 5 minute walk to both of the metro lines we used most, including one connecting directly to the train station. Just minutes from Plaza Mayor, yet once the windows were closed it was wonderfully quiet. Everything was clean and very well maintained. The elevator was perfect for our luggage, especially since traveling with an infant. The hosts communicated early to ensure our arrival was smooth. Bed was comfortable and two AC units which is a must when it gets warmer. We made good use of the washing machine to reduce the amount of luggage we brought. Highly recommend if you want something convenient to the main sites but quiet in the evenings to be well rested!
