Paula reached out to me via texts with clear instructions on check-in. She even assisted to arrange airport transfer on the day of check-out! Carlos, on the other hand, was present physically at the entrance to assist with the check-in and to show us around the apartment. Kudos Paula and Carlos!!! Also, Toni the driver arrived on time and helped with our luggages on the day of check-out! The airbnb is situated strategically at the Metro station - Plaza de Espana which is few stations away from Callao/Gran Via/Sol where the shopping heaven is at. You can also walk about 10 minutes! The area is safe even when you get back around 9/10pm! It's near Carrefour Express if you need essentials but be mindful that it closes at 11pm. The apartment itself was great too. Thank you again!
