David's place is a great little place in Madrid. I stayed here with my sister and we found it to be a perfect size for the two of us. David was great, we got into Madrid early in the morning and he let us stash our suitcases at his place while he was getting the apartment ready, even though he didn't have to do so. Great amenities in the apartment, including laundry and dishwasher soap, as well as kitchen essentials. The flat is right on the number 2 Metro line which can get you to Sol in 15 minutes or so. The bathroom is down some windy steps, so if you've got mobility issues it might not be the best choice, but we didn't find it to be a problem at all. Would recommend staying here!
