Carlos has a very beautiful and artsy flat, with lots of plants and perfect for a short or even longer stay for two people. you got the whole flat for yourself and we felt home as we walked in. you got everything you need, in the kitchen and also in bath, livingroom and bedroom - from hairdryer to netflix account, your wishes will be heared. at weekends it can be a bit loud from the outside (if you want to sleep with open windows) - but thats what it is if you want to stay in the mittle of the city. its the very perfect location to walk to almost everything you want to see. would recommend 100% and love to stay at carlos flat again if im back in madrid. have fun!
