Location was great, right in Puerta del Sol. So convenient, really close to the Metro Sol station and close to the hop on hop off, Madrid city bus tour stop. It's located on a busy street, convenient to shops and restaurants. The location really couldn't be better for us. The door locks were a little difficult to open at times, especially the front door, but other than that our stay was very pleasant. The set up is open and amenities were as needed. It was around the time of San Isidro festivities so there were a lot more people out and a lot of noise the first night. There were earplugs that are offered upon entrance to the apartment, but we didn't use them at all. During the day the noise level isn't bothersome. One thing that we didn't enjoy so much was the bath towels. They had a foul stench to it as if they were not fully dried. That was our only complaint to the place. Overall, we really enjoyed our stay, really loved how the location was so easy and convenient for us to sightsee, shop and eat. Would definitely stay here again.
