Honestly I'm a bit confused about the high rating and positive reviews on this listing--
A few big cons of our stay were 1) Overall the apartment didn't feel very clean or sterile. The kitchen was especially messy and we didn't feel like we would want to utilize it even if we could. But our room itself where my friend and I stayed was clean 2) The other guests--I've stayed at airbnbs where we have to share the space with others and that's totally fine with me. But here, the other guests (presumably in their 20s) were playing music loudly and were rather disruptive until pretty late into the night. It almost felt more like a college dorm than a home to come to 3) The cats--I knew there would be cats beforehand, but I wasn't prepared for them to dart out of nowhere into our room and hide under our beds several times. They walk all over the apartment so keep this in mind if you're not a cat person.

The pros: 1) Carmen was really sweet, friendly, and welcoming. 2) Our beds were comfortable and there were two huge closets with many hangers in our room 3) Reliable wifi 4) Close (15 min. walk) to Atocha station, which is a main station where you'll find busses to/from the airport, metros, trains, etc.

Overall, I can't complain much because the price was rather low and I don't regret staying there, but I wouldn't recommend it to my personal friends and family.
