Don't be deceived by the listing, 1b does not mean 1 bedroom. 1b is the apartment number. This place is an extremely small studio, with a very very very small bathroom. If you run the shower for more than 2 minutes, you need to shut it off and let the water drain, because it backs up quickly.
The "garden view" is just a couple of plants on a roof top, accompanied by scrap wire and garbage.
If you're traveling solo and don't plan on spending time in the place you're sleeping in, the place is fine. But if you're looking for some comfort, look elsewhere.
