Absolutely perfect location - very close to Plaza del Sol, in the heart of the famous Madrid clubbing scene and with some amazing restaurants nearby. That said, the apartment doesn't get any noise at all when the windows are closed - with AC in every room, it's very comfortable. The apartment itself is very cozy, clean, professionally maintained, with well stocked kitchen and sufficient amenities (bring your own shower toiletries though although hand soap is provided). Check in was a breeze as Gonzalo, our designated host, was waiting for us outside the apartment building when we got off the Uber. Since we were 5 people and taxis in Madrid don't take more than 4 passengers, we had to book a van to the airport, which Gonzalo told us about upfront. I sent a message on Airbnb to Ramon and he promptly booked the van for us at the standard rate, which arrived ahead of time when it was time to leave. Overall, a great experience and would definitely stay there if I visit Madrid again.
