We had a great time at Raul and Susana's place near Plaza Mayor, which acted as a great base for us to rest in the evenings after exploring the city. The flat is perfectly located for sightseeing as it is about a 3 minute walk from Puerta del Sol and not much further than that to the Royal Palace or any of the other main sights in that area of town. The apartment is on a side street just off some much busier streets and so though you can hear some of the usual city centre noise, it is nowhere near as much as you would expect given the location (the living room and kitchen area (air conditioned) is on the street side and the bedroom (fan is included) on the quiet side round the back). The apartment was very clean and was a great size for us. Susana was a superb co-host, meeting us at check-in and giving us some useful tips for the city. She also kindly called us a taxi for our very early check out on our final day.
