HOST: Carmen is extremely warm and welcoming. Carmen shared her coffee and pastries with me in the morning, and patiently answered my questions (in Spanish). Please note, Carmen's son smokes on the balcony so if you are extremely sensitive to smoke, you may wish to look elsewhere
ROOM: The room is simple and just what I needed. I brought earplugs, but the apartment was quiet. The other thing that is very important to me is a firm bed. This one is fairly firm, but you can feel the springs. It didnt' bother me, and I slept like a rock (of course I spent just one night after 23 hours of travel!). There is not much spare space in the room, but if needed you could do some push-ups or roll out a yoga mat.
LOCATION: The location is 4 minutes walking to the train station. I am not sure you could get any closer! You can easily walk to the old part of town and see amazing architecture, churches, tapas bars, flamenco bars and more. The Cathedral is about a 20 minute walk away. Overall an incredible deal.
AMENITIES: nothing fancy, but you have access to a whole kitchen, and of course a bathroom with shower (you may need to ask how to pull the switch to get the shower on). You will want to bring your own converter for electricity if needed as there is none provided. Wifi worked perfectly -- I connected through the AirBnB app while I was waiting outside -- nice one, AirBnB.
