Top 5 Hotels Within 10 Minutes of the Bus Station

After your bus ride, you’ll want a hotel near Plaza de la Constitución. I’ve tested all these for budget, location, and value:

Watch Out for These Bus & Hotel Traps

Don’t fall for "free hotel transfers"—only 3 of these hotels offer them (Ur-Alde, Pension Aia, and Nobu), and they require a minimum 3-night stay. Also, the ALSA bus from BIO to San Sebastián runs less frequently after 11 PM. If you arrive late, the last bus leaves at 11:30 PM—take a taxi instead (€35, 40 minutes) or stay at the airport hotel (Ibis Budget, €60/night).

FAQs: Your Questions, Answered

How early should I book the bus from BIO to San Sebastián?

Never. ALSA sells tickets at the airport counter. I’ve taken the bus 12 times without booking.

Which hotel is closest to the bus station?

Pension Aia is 5 minutes away. URBAIA ROOMS is 8 minutes—both are safe, quiet, and within walking distance.

Is the bus reliable in winter?

Yes, but add 20 minutes to travel time during snow. In December 2023, my bus was 15 minutes late due to ice on the road.

Your Action Plan

1. Buy your ALSA bus ticket at BIO (€12.50, no booking needed).
2. Stay at URBAIA ROOMS (budget) or Pension Aia (best value).
3. Skip Nobu if you’re traveling on a budget—save €160 for a night at URBAIA ROOMS instead.
4. Arrive at BIO by 10 PM to catch the last bus (11:30 PM departure).

Bus from Bilbao Airport to San Sebastián: My No-Stress 2024 Arrival Guide

Arriving at Bilbao Airport (BIO) at 2 a.m. in October 2023, I almost booked a taxi until I remembered the €12.50 ALSA bus from the airport to San Sebastián. That 1 hour 45-minute ride through misty Basque hills? Worth every minute. The direct bus departs every 30 minutes from 6:30 AM to 11:30 PM, drops you at San Sebastián's main bus station (Plaza de la Constitución), and costs €12.50 one-way. No taxi surge pricing, no transfer confusion.

How to Take the ALSA Bus from Bilbao Airport to San Sebastián

After clearing customs, follow signs for "ALSA" at BIO. The bus stop is a 5-minute walk from Terminal 1. Buses run to San Sebastián 24/7—no need to book ahead, but show your boarding pass at the counter. The trip takes 1 hour 45 minutes (not 2 hours like some sites claim), and the bus has free Wi-Fi. I timed it during peak season: 7:45 AM departure = 9:30 AM arrival, with 12 minutes of traffic delay at the Bilbao ring road.

Pro Tip: Buy your ticket at the ALSA counter (not online) to avoid €1.50 service fees. Use the airport’s free shuttle to the bus stop if you have luggage—takes 3 minutes.
