Is it a good place to stay for 10 days?

Sounds perfect. Make sure to ask whether you're allowed to bring a girl back to your room. Some places are pretty strict about that. That's the place with the most working girls, so if you're staying 10 days you probably already know. And if they say yes, here's the next question: ask whether you can bring a different girl the next night. Some places get weird about that too.

Have you been to Singapore? That's a place where you can actually spend 10 days in one city. You might not have the money for it, but if your budget is tight, I'd pick Bangkok among the Southeast Asian cities. Try posting the same question on Passport Bros. You seem exactly like their kind of guy.

Oh my god, no matter which neighborhood or hotel room you stay in, Manila is not Rome, Prague, or Istanbul. Wherever you stay, you're in a big city in a developing country. Delhi would honestly be better. Still, have a nice trip
