Celina's flat was a lovely experience. Located in Moncloa, it is near central transport, great restaurants but it still within walking location to more central locations like Chueca, Malasana, Chamberi, etc. Having lived in Malasana for a few months before moving to Celina's, I enjoyed the solitude and relative quiet of the space in comparison to more crowded areas of Madrid. I never took the metro, but if you choose to do so it's less than an hour to the airport and within minutes to Gran Via and multiple tourist sites. The home was sparkling clean. I especially loved the shower fixture in the private bathroom. :)
Celina and her brother are really lovely people and made me feel nothing but welcome. We have a lot in common so we spent time discussing a variety of topics, though our schedules were not in sync. Next time I am in Madrid I will be looking Celina up! You will leave the flat with not only a great Madrid experience, but with a new friend, too! Highly recommended and what airbnb should be! Muchas gracias!
