The area is a relaxed residential beach neighborhood, located between the upscale touristic areas of Condado and Isla Verde. It has managed to retain a residential feel, with local restaurants and boutique shops.
The neighboring Loiza street is very commercial, and you will find a large supermarket a 5 min walk from the house (Plaza Loiza has a large choice of fresh products and is open everyday from 6am to midnight), gas station and pharmacies. Calle Loiza has been experiencing a growth in recent years, with young entrepreneurs & artists, fancy restaurants, bars, street food, bakeries, cafés etc.
