Summary: Great breakfast with handcrafted coffees. Fruits, especially fresh berries SWEET and fresh! Room small but rather functional. Bed firm but that’s how I like it. Bedding with starched cotton duvet cover - wonderful! That’s what I’m used to from hotel bedding in Europe. Front desk super nice to store my luggage before my meeting and on the last day of my meeting, after early check out in the morning. Easy 11 minute walk to Moscone Convention Center. Now I’m going to watch for citizenM Hotels!
