Had some issues with check-in, the keys were provided in a lockbox at a different address and then the keys were not able to open the door once I arrived as the key to the second lock on the door was not provided (it was locked by mistake). The host was quick to respond and was with me after about an hour of waiting, which I appreciated her responding as fast as possible but it did cause me to be late for a dinner I had planned. The power breaker in the apartment also got tripped twice while I was there, waking up to a phone that didn't charge overnight was a bit annoying. Overall the place was clean and comfortable, and the location couldn't be better! At the price, I would say it's a fair value in the end and a good choice for most people coming to Madrid for a few days.
