I stayed in this property with a friend while attending a conference in September and was disappointed with the experience (we ended up moving to a hotel near Union Square for the last 2 nights). Firstly, I would not describe this as a boutique hotel - perhaps “Apartment Hotel” or just “Apartment” would be more accurate. The facilities, while clean, were pretty basic. The actual apartment was dark and small, with two bedrooms and a toilet/shower room only (it would be helpful to state the square area) and the level of furnishing was basic. There is a single common area for the entire building which has a coffee machine and a shared fridge that residents can use to keep their own food/drink in. There is no kitchen/stove/cooker to even make yourself breakfast of a morning. Secondly, there is no air conditioning in the building. During our stay it was very hot and we had to open the fire escape door in the common room to stay cool. Each room had a fan but I had to sleep with the windows open (which meant you had all the street noise coming in. Third, while the Hayes neighbourhood itself is nice with several restaurants and cafes, it is more than a mile from the Union Square/Moscone centre area - we had to take Ubers on most days as it is too far to walk. I would not stay in this property again.
