Best spot to do whatever you want around L.A, the metro station is literally downstairs (Red line/prl line, connection a station away for Santa Monica at the 7th Street's stop) and the business district, The Broad, L.A live etc. are really close. If you're looking for the OUE Skyspace experience, you are 5 minutes away walking!
The apartment itself is clean and spacious despite being a studio, more than enough space for one person but could easily fit 2 or 3. Despite being in the middle of the DTLA Action, the unit is surprisingly quiet so don't worry about resting properly.
There are a lot of stores around (1 walgreen and 1 Rite Aid facing the building and wholefood is 10 minutes away walking. Target in a mall a little further.
Amar is available for queries and gave great pieces of advice for sightseeing/eating in L.A. Don't hesitate to ask him if there's a certain place you'd like to visiy, he might have a few tips for you!
Great view from the rooftop, I'd advice staying there at dusk to see the city lighting up while enjoying afterglow reflected on skyscrapers.
I've stayed there for 2 weeks and will gladly come back!
