We had an excellent stay at Room Mate Mario. The check-in process was seamless and the staff was incredibly accommodating. We arrived early and, although our room wasn’t ready yet, they gave us a clear timeline of one hour and provided a great recommendation for a local brunch spot nearby. True to their word, the room was ready exactly an hour later. The location is absolutely perfect, it’s very close to Gran Vía, but tucked away enough that it isn't chaotic. It felt very quiet and safe at all times. If you are driving, there is a public parking garage very close by which made logistics easy. The room itself was very clean. We did experience a brief power interruption during our stay, but it was an issue with the local area, not the hotel itself. I was very impressed with how the hotel handled it; they notified us immediately when the power went out and followed up right away to check on us once it was back on. Great communication and a wonderful stay overall!
