Marta's place was reliable, clean and perfect for what I needed for one night! It's on a bit of a noisy street with a few restaurants downstairs so I would recommend this for a short term stay. The host is very nice and was there to help me check in and make sure I had everything I needed. Communication was also great as Marta responded to any and all questions I had in a timely manner. I recommend you to book Marta's place when you're in Madrid!
