Planeta Cadiz Hostel

Planeta Cadiz Hostel sits on Calle Montañés, a narrow Casco Antiguo street two minutes from the small La Caleta beach where the locals swim and four minutes from the cathedral. The address is the cleanest of the two viable Cadiz hostels: the Mercado Central is six minutes north, Plaza San Juan de Dios eight minutes east, and the train station is a flat 12-minute walk. You're inside the historic walls the entire time.

The building is a restored 19th-century casa gaditana — high ceilings, an interior patio with the standard Andalusian arch and azulejo tile, and a small sun-trap terrace where guests gather mid-afternoon. Dorms are 4–8 bed, each bunk with a curtain, reading lamp and lockable storage. The breakfast — included with every booking, served from 08:00 to 10:30 — is rare territory for a Spanish hostel at this price point. Continental plus vegetarian, vegan and gluten-free options. Coffee from a real espresso machine, not a vending unit.

Check-in is via an automated kiosk that runs 24 hours. There's also a real human at reception during the day, friendly and locally knowledgeable, but the kiosk means a 03:00 train arrival from Madrid Atocha works without drama. Free Wi-Fi throughout, a shared kitchen for guests who want to cook, and the courtyard doubles as the social space because there's no on-site bar — Cadiz's drinking life happens at the tapas bars in La Viña, three blocks away.

Reality check: this is the hostel for travelers who want to walk to everything, eat tapas at midnight on Calle Virgen de la Palma, and cap evenings at the hostel terrace rather than a pub crawl. There's no organized nightlife and no rooftop. Pick it for sightseeing-driven Cadiz trips and surf-day-trips down the coast; pick Casa Caracol if you came to Cadiz primarily to surf and want bike rental and surf lessons handled in-house.
