Very nice apartment. Comfortable and well equipped. Some nice touches like having coffee, an espresso pot and a tea selection.
The location is good. It's part of Plaza Mayor which is a major square in Madrid. The square is surrounded by restaurants and shops. Yes, some of these are kind of touristy, but on the other hand, we were tourists. And, despite being a major, busy square, the apartment was amazingly quiet as the windows did not face the square.
Nice to have a washing machine and although there isn't a drier, there is a drying rack and our clothes dried pretty quickly.
We would have given a higher rating but there were two significant issues.
First, the check-in arrangements were changed at the last minute. And, we had no way to receive them while on our flight. So, when we arrived at the apartment as previously arranged there was no one to greet us. This resulted in us having to make an expensive call from our US cell phones to find out the new plans. There was a communication gap at check-out that caused us considerable stress as well. Better communications will solve these issues.
Second, homeless people take over the square in the evening and set up a cardboard box village along the perimeter of the Plaza. Both sides of the condo doorway had homeless people sleeping along side of it. Frankly, they did not hassle us for money and we didn't bother them. But, it is probably something you will want to be aware of.
