Madrid is noisy. All the time. And despite the hotel's best efforts at soundproofing, I didn't get great sleep on my first night because of the noise of party-goers and traffic outside. The receptionist had told me that this wouldn't be a problem, but it was. By night two, I had invested in earplugs! Also, I wasn't offered any help with my luggage when I arrived, despite having three cases. Finally, I felt that the breakfast was over-priced and wasn't well stocked; though when I asked for something fresh to be cooked, it wasn't a problem.
The room was spotless, the bed was so comfortable I didn't want to get up in the morning, the blackout blinds kept the light out at night. The staff were helpful and friendly, even agreeing a fare to the airport with the taxi driver as I was leaving. The location is OK, if not the best in town; but it's close to the restaurants and bars of the Plaza Mayor, and there are two metro stations nearby (the Madrid metro is excellent and cheap, by the way). So getting to the parks and museums is no problem. I would stay again for the comfy bed and the great staff.
