We really enjoyed our stay with Raul. The apartment has everything you need. It’s on a street in Madrid so you should expect some noise but that’s totally normal in such a central location.
There was some confusion about the second set of sheets not being there and we had to spend the first night without them. Raul responded immediately to our messages, though, and while he could not solve the problem immediately he made sure it was solved the next day and he also offered a small refund.
