Carlos was a fabulous host - he was so helpful before we even arrived and then throughout our stay. He offered many recommendations for food and other things we needed. The apartment is lovely and the location is fantastic - especially the amazing views. The bed is quite firm. Bathroom is small, classically European. There is a wonderful cross-breeze through the apartment when the windows are open.
Location is great - fairly quiet street, just down the side stairs from the Sacre-Coeur. Less than 10 minute walk to the 2 and 4 metro lines.
