Ruben's place was very central. We were walking distance (10-20min strall) from all main attractions. There were a lot of lovely bars and restaurants around us, some literally a street or two over. The place itself was comfortable, clean and cosy and it had everything you could need away from home - washing machine and deterget; shampoo, conditioner; cooking amenities - it made things so much easier. Ruben had some great tips and was also very quick to respond to any questions. I would highly recommend Ruben's place to anyone staying in Madrid.
