The Presidential Suite is described as having an expansive terrace with terracotta tile and wrought\-iron furnishings, which provides an outdoor setting for candlelit dinners of up to 40 guests\. The suite itself is 861 square feet and includes a separate living room, dining area, king bedroom, and two bathrooms\. ### Can this property host meetings or team gatherings in an outdoor\-event space? Yes\. The property’s rooftop lounge, Sunbird, is an outdoor space with open\-air seating, so it can suit meetings or team gatherings in an outdoor setting\. Separately, the hotel’s lobby is described as a space for connection and calm, but that is indoors rather than an outdoor\-event space\. ### Is breakfast available for a stay in guest\-room\-standard? Breakfast is not included as standard for citizenM stays, and it may depend on the rate or package booked\. Guests can check their booking details or add breakfast where available\. ### Does the King \+ Balcony in guest\-room\-standard include a balcony that guests can use? Yes\. The King \+ Balcony room is described as having "your balcony" that guests can step onto, which shows the balcony is part of the guest room and usable by guests\. The visual evidence also shows a private room with floor\-to\-ceiling glass doors leading to that balcony\. ### At the suite spaces, is there a full in\-room kitchen available in any room type? Yes\. The TownePlace Suites brand page says suite types such as the King Studio Suite, One Bedroom Suite, and Queen\-Queen Studio Suite each feature a full kitchen, and the brand overview also states that suites are made for one to four guests with full kitchens\. I did not find any evidence here about the AC Hotel suite spaces specifically, so this support applies to TownePlace Suites room types only\. ### Does the dining area include customizable breakfast options for guests? Yes\. TownePlace Suites states, “Free Breakfast” with “customizable options,” which directly supports customizable breakfast offerings for guests\. However, the evidence does not show that this applies to AC Hotel San Diego Downtown Gaslamp Quarter specifically, so I can only confirm the breakfast feature on the TownePlace Suites brand page\. ### Can guests work or relax in the lobby at this property? Yes\. The property’s lobby is described as an open, refined space with lounge seating, a sunny morning lounge that becomes an evening retreat, and a breezy indoor\-outdoor patio flow, which supports both working and relaxing there\. The AC Lounge is also described as transitioning from a productive daytime workspace to a vibrant evening gathering spot, with seating and a bar counter\. ### Are the guest room standard spaces designed for guests to work or relax between meetings? Yes\. citizenM says its hotels are designed with flexible living room spaces where guests can work, meet or relax, and that they are designed for travelers who want comfortable spaces to work or relax between meetings\. The room visuals also show guest rooms with a workspace setup, including a desk/workspace seating, which supports working in the standard rooms\. ### Does the lobby have a place to store luggage before check\-in or after checkout? Yes\. Marriott’s FAQ says there is luggage storage on\-site: if you arrive before your unit is available or check out and want to explore some more, they offer luggage storage\. The same FAQ notes check\-in is at 4:00 PM and check\-out is at 12:00 PM\. ### Is there a rooftop lounge in the outdoor\-event space that guests can visit for dining or drinks? Yes\. The property’s Sunbird rooftop lounge is described as an elevated open\-air space with outdoor bar service and cocktails, and the visual evidence also tags it as having outdoor dining\. It is presented as part of the hotel’s rooftop amenities, so guests can visit it for drinks and dining\. ### Can guests use the Marriott Bonvoy app to get recommendations during a stay in the guest room standard? Yes\. The Apartments by Marriott Bonvoy FAQ says guests are encouraged to download and explore the Marriott Bonvoy app to access recommendations from the digital concierge, and it also notes that a host is available on\-site for check\-in and check\-out\. I could not verify the same app recommendation feature specifically for this AC Hotel property or for a “guest room standard” booking type from the evidence provided, but the Marriott Bonvoy app recommendation feature is documented for Apartments by Marriott Bonvoy\. ### Is there a fitness space available for guest use during a stay? Yes\. The property includes a fitness center with treadmills, stationary bikes, and free weights for guest workouts during a stay\.
