Vrbo listing optimization is the work I do to make a property rank, convert and price correctly on Vrbo. I rewrite your headline and description for Vrbo's family and group guests, order photos to sell the whole home and tune rules and settings.
What I plan around in Barcelona: Mobile World Congress; Primavera Sound and Sónar; Beach season and cruise arrivals; FC Barcelona fixtures. Guests I price for: European city-breakers and cruise passengers on 2 to 4 night stays, with longer summer stays near the beach. Where I start: Licensed tourist-apartment pricing, MWC premiums that start a year ahead, and length-of-stay discounts for the shoulder months.
Barcelona sells mostly through Airbnb, Booking.com and Vrbo. I set your Barcelona pricing so MWC, Primavera Sound and summer dates are loaded with premiums and minimum stays, shoulder months use length-of-stay discounts, and Airbnb, Booking.com and Vrbo all show consistent rates and tax, while the calendar respects the city's rules on which licence the flat holds and how it may be marketed.
The service in general is described on my vrbo listing optimization page; this page covers how I apply it in Barcelona.
