I stayed at Daniel's apartment with my friends. It was a studio apartment with one bed and one pull-out couch. It was small, but the perfect size for sleeping. We used our time exploring Madrid and of course shopping. The apartment is literally the best location. A minute walk from Sol in one direction and Plaza Mayor the other direction. The apartment was very clean when we arrived. The door code and check-in box were manageable and easy to use. The bathroom is fit for one person. There was a sewage smell from the bathroom after the first day, but it did not bother us too much because we spent most of our time exploring the city. We loved having the balcony for the morning and evening. Daniel was quick at responding and accommodating. He helped extend our trip an extra day when our travel plans were switched. I would stay at Daniel's apartment again. Thank you.
