The property itself was amazing. It was clean, fully-equipped, and even the check-in time was also flexible for us. And the location was also great that metro & bus are all walking distance (around 3 or 4 mins).
However, the neighborhood was absolutely terrible that I and my friends couldn't sleep at all for 3 nights, literally. It's because there're just too many drunken people out there (even at 3 or 4AM) and they're screaming, playing hard-rock kind of music, and fighting as well.
And the neighbor just next to this house had a fight one day, so a bunch of police guys came at 6 in the morning, and shouting like 'Policia, Policia!' And you know what? They kind of bombed the door (we thought it's like a terrorism or something) and they arrested everyone from the house..
So what I want to say is, if you have a state-of-art earplugs from Steve Jobs, go for it. Otherwise, you'll never get to sleep.
