The place in general is a good cheap place to split between 4 people and is on the outer banks of the heart of madrid. The area is a bit sketchy and the walk to the apartment is also a bit sketchy along with the key used to unlock the door, took us about 10 minutes each time to finally get the door to open. Noise isn't too bad but the power went out during our stay and we did not know how to reset the power and didn't want to press anything we weren't supposed to, and our host didn't reply at all during the power outage or during check out so me and my friends got a bit worried towards the end as the host sent someone to check us in and that same person was supposed to meet us at checkout, but never arrived so we had to leave for our flight without meeting with whoever our host had sent to collect the key. Overall not the best experience and i would recommend paying the extra 20-30€ to stay somewhere closer to the heart of madrid as well as somewhere safer and cleaner.
