My boyfriend and I had an amazing stay in the speckles suite! The huge room was nice for spreading out our things to get ready in the morning, I loved the access to the continental breakfast for a quick snack in the morning and endless coffee! The bathroom is huge, we had plenty of space to get ready for the day quickly. Great location and staff, the room was exceptionally clean. Will definitely be back!

Loved my short stay. The hotel was surprisingly quiet for being right on Union Square. It is a very old building with appropriate quirkiness, but they have upgraded the bathrooms which is fantastic. Very friendly and helpful front desk staff. The continental breakfast is a fine offering - pastries, toast, bagels, cereals, yogurt, and of course coffee, but served in a small room with a communal table, so be prepared to get to know your neighbors! Best parking option IMO is to park across the street and down a half block at the Union Square grarage - that costs $46/night, and for San Francisco, that is a very good deal. The other hotels charge $75-$100 per night for parking.

Staff was amazing - rooms are small but clean. Queen bed was NOT a queen but a double. Breakfast was poor and one day they had no coffee after 8:30 even though breakfast is served till 10:00 am. Area is very central to everything but not the best area in the evening with the homeless / lots closed down you have to know where you are going. Staff at the hotel was helpful and wonderful!

This hotel does not having air conditioning. I would not have booked it if I had known that. However, it had a great ceiling fan and I was comfortable. My husband runs hot and he was not comfortable. The bathroom was super clean and I was happy with that. It was a good location catty corner from Union Square and a short walk to the Powell Station and cable cars. Overall it was a good value.
