This is a perfectly fine and safe place to stay in a convenient location within the Gaslamp District.
There are two comfortable beds but, because it's a loft, there are no walls so privacy is a bit of an issue. The first bed is next to the front door, and the second just around a corner. Might not be the best layout for multiple couples or parents hoping to "honeymoon" away from sleeping children (if you know what I mean).
This is a rented space in an apartment building so look out for several rules about behavior and noise. Amenities are present yet minimal so make sure to bring what you need. TV and Internet work great but we had to wrestle with set up a bit, could have used more instructions. Check in instructions were lengthy and thorough but a little later than normal (4pm) so make sure you have a plan for the first part of the day. Washer/dryer are convenient but loud, dryer ruined two items of clothing.
Host was responsive and helpful both before and during our visit.
