Hotel Details

Location

In the vibrant Gaslamp Quarter, this hotel places you within a 10-minute walk of the Convention Centre, Petco Park, and dozens of restaurants and nightlife venues.
The hotel sits on Fifth Avenue in the centre of San Diego's nightlife district, with bars and clubs operating until 2-3am. While this provides unmatched access to entertainment, it also means street noise is significant, especially on weekend nights. The Convention Centre is less than 1 km away, San Diego International Airport is 4 km, and Seaport Village and Little Italy are within a short walk or ride. Public transport (trolley and bus) is easily accessible, and walking is the best way to explore the area. Valet parking is available, but off-site garages offer lower rates.

Accommodation

Air-conditioned rooms with private bathrooms, work desks, and tea/coffee makers. Some rooms offer balconies with city or Gaslamp views.
Rooms are modern and clean but compact. Each includes a flat-screen TV, safe, iron/ironing board, hairdryer, and free toiletries. Bed configurations include king, two doubles, or one double - specify your preference at booking. Rooms on the Fifth Avenue side or adjacent to nightclubs experience high noise levels until late; rear-facing rooms are quieter. White noise machines and earplugs are supplied. Balcony rooms are available but not guaranteed; request directly. The décor is contemporary with a boutique feel. Housekeeping is provided daily but may be inconsistent; contact the front desk if service is missed.

Dining

AC Kitchen serves a continental breakfast buffet ($24) with champagne, hot dishes, and fresh pastries. AC Lounge offers dinner and a full bar.
Breakfast is available weekdays 6:30-10am and weekends 7-11am, featuring a European-style spread with local specialities, warm dishes, juice, cheese, and fruits. Dinner at AC Lounge runs from 5pm to 11:30pm (until midnight on Friday and Saturday) with a modern, family-friendly menu. The rooftop bar operates seasonally (usually Thursday-Saturday) and offers cocktails and light bites. Snack bar and room service are also available. For those wanting a wider selection, the surrounding Gaslamp district has countless dining options within a short walk.

Wellness and Leisure

A rooftop heated pool and sun terrace, fitness centre, and pool bar. Activities include free evening entertainment and walking tours.
The rooftop pool is open daily 9am-8pm (weather permitting) and is heated to 81-27.8 °C year-round. It features a pool bar and sun loungers, but can be busy on weekends - pool parties sometimes occur, limiting general access. The fitness centre is free and includes cardio and weight equipment, plus yoga and fitness classes. Additional paid options: massage, golf (within 3 km), and various tours. The hotel also offers free evening entertainment such as karaoke, movie nights, and live music, plus walking tours (additional charge). There is no jacuzzi on site.

Free WiFi, valet parking, 24-hour front desk, luggage storage, and business centre. Pet-friendly with restrictions.
Parking is valet-only at $62 per night; the nearest off-site garage (Horton Plaza, 4th & F) is about $15 per night. The hotel offers express check-in/out, free luggage storage, and a 24-hour front desk. Business services include a business centre, meeting/banquet facilities, and fax/photocopying. Accessibility features: wheelchair-accessible entrance, raised toilets, grab rails, Braille and tactile signs. Safety includes CCTV, key card access, and smoke alarms.

Top Strategic Tips

  • 01

    Request a room away from Fifth Avenue and the nightclub side if you are a light sleeper; earplugs and white noise machines are provided but may not eliminate noise.

  • 02

    Save on parking by using the off-site parking garage at 4th and F Street (approx. $15/night) instead of valet at $62/night.

  • 03

    Plan your arrival: if 5th Avenue is closed (evenings/weekends), valet drop-off is at 511 F Street. Check-in is at 16:00, but luggage storage is available free of charge.
