Cristina's place was fantastic! It was located excellently infront of Atocha Station where you can catch a bus, metro, or train anywhere you need to! It's a few blocks away from some of the most fun night clubs in Madrid, and extremely close (about 5 minute walk) from Parque del Retiro. The place is nice and cozy, definitely fit for a couple. When I arrived there was a very kind girl waiting for me who explained absolutely everything about the apartment and where everything was located. The fridge was stocked with water, and there were pots and pans for cooking whatever we needed to. We really enjoyed our stay here. PS: they were kind enough to hold onto some important documents that I had forgotten during checkout, and practically saved my life. If I could give them 6 stars I would. Thanks for everything!
