I stayed at this unit for 2 nights and here are some insights on this location:
1) Location:Pro- I would say that the place is really close to some good bars and restaurants. It is about 15 min away from the Wilshire/Normandie subway station, which you can take to go to downtown LA or Hollywood. There are a few breakfast places nearby but there are a bunch of cafes that you can go to to grab coffee. Con- This is more of a critique of the neighborhood than the unit but it can be quite sketchy at night (i.e. building residents that prop the back door entrance leave the entire building susceptible to break-ins).
2) Amenities: Pro- There is a full kitchen that is fully stocked with utensils, plates and cups. There is a gas stove and water dispenser although you will need to refill that water yourself. The bed and sofa bed is very comfy. The linens and blankets were soft and clean. The bathroom was a half bathroom but it had a big tub! Marina also has a well stocked first aid drawer. There is a TV but I didn't really use it during the trip. Also there is wifi, which is good for business trips. Con- This is more of a critique of the building than the unit but the building does not seem wheel-chair friendly. There is an elevator but to get to the elevator from the main lobby you need to go up a few steps. There is a heavy door that you will also need to open before riding the elevator, which could be difficult for physically disabled travelers.
3) Cleanliness: Pro- The beddings and kitchen were clean. Con- My main critique would have to be the carpet, which could use some extra cleaning as it was dusty.
4) Value: I think the value of the unit was ok and that you are really paying for the proximity to downtown LA and other tourist spots.
Overall: I would recommend this place to travelers if you need a place to stay and sleep at that is nearby downtown LA. For families with young children this might not be the best option, which Marina pointed out in the description of the place.
