We stayed at Indigo Hotel three nights during our trip along the coast of California where we choose to stay mainly the Holiday Inn Express.
It was the first time we stayed at a Indigo Hotel and there are a big difference between this Indigo San Diego Gaslamp Quarter and the HIE.
The rooms have enough space, the bathroom was fine the internet was ok and the service fine also.
However the big difference is the decoration much more young and agreable than the HIE and we were already fed up of the HIE.
The unique problem was the noise during the first night because our room was close with the vending machines, but they changed us to another room and the problem disappear.
For us this Indigo is a very pleasant hotel and we recomend it..
