12 out of 10 stars! Rosa María’s piso is clean, modern, quiet, welcoming, and has amazing A/C for the summer heat. The shower is a dream, and the kitchen is very well-stocked; we did not need to purchase any condiments or even coffee. Rosa María was available through the app, though she also provided her cell number. We got great recommendations from her at check in, and had access to myriad books and maps of Barcelona. The beach is a block away, and there are chairs and umbrellas in the apartment.
One very special detail: Rosa Maria texted me a few days before our stay asking my kids’ ages so she could leave some age-appropriate books and activities for them.
