The good:

It's great to be only two blocks from the beach in Leblon!

The bad:

This apartment is on a very busy street--maybe the busiest in Leblon. There are constantly large trucks driving by in the late night and early morning. It's not pleasant having the windows open with all that noise. If I'm in Rio in the winter I want my windows open when I'm sleeping!

During the time I stayed, there was also construction on the new metro station across the street so this also caused noise early in the morning, even on a Saturday morning.

The loud noise was stressful. I couldn't relax in the evening and couldn't sleep in in the morning.

In general the quality of apartments in Rio de Janeiro is pretty low. Most of the apartments are old-fashioned and poorly furnished. This was par for the course. Not really comfortable. But you won't find better apartments unless you're willing to spend a lot more money. I'd say that if it weren't for the noise this would be a good place for the price.
