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!

Everything was fine, nothing was obviously dirty but it was old and mildly renovated. We stayed in a clean King Studio the bed was soft, room was somewhat spacious with a large smart TV and the restroom was clean with new fixtures. However, there was a stale/chemical smell and the power for the room's outlets is on one switch. There is only one somewhat shaky elevator, refreshments and breakfast treats were provided. There is no additional parking and the area around the hotel is a little sketchy, you shouldn't be out once it is dark...

Great central located hotel. Parking is $40 per day so I highly recommend to arrive with the car to the front of the hotel and park there for about 15 minutes which is allowed by the hotel. check-in, unload your luggage and bring it up to the room. Go back to your car and start driving around and using the car before you park it for the duration of your stay. Go see and drive down Lombard street, go to the Golden Bridge Park, drive up to the telegraph hill, drive down to the fishermen word and only then, late afternoon park the car and leave it until you leave San Francisco. The hotel staff were very nice, it was a hot summer day and management sent us to the room a portable AC which was great. Highly recommend the hotel for people who wish to be in the center of it all and love to walk.

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!
