W San Diego
We recently stayed at the W Hotel in San Diego. The lobby is very funky and welcoming. The front desk staff were extremely helpful and friendly. The rooftop bar is comfortable and a great place to have a drink. The rooms were well appointed in a boutique style. The bed and linens were nice and comfortable and I appreciated the bathrobe in the room. 
The hotel is within walking distance of Little Italy, the Gaslamp District and many other nearby attractions. Public transit is readily accessible, as well.
I would not hesitate to recommend this hotel to others.
