Great stay in Madrid - great location. Super quiet apartment and was able to use space in the fridge and use the kitchen. It was more of a guesthouse as there were a few floors of people staying there and sharing the kitchen and bathrooms. Great spot for backpackers as it is affordable and a great spot. Major flaw was no fan! It was really hot which we expected but really could have used a fan at night. Also the oven doesn't work in the kitchen which could be fixed. Didn't met Charlie as they were on holidays but their friend was very helpful with everything - even showed us how to cook pizzas in a pan :) Thanks for the stay! Would recommend.
