It is free to enter the enclosed neighborhood but be prepared to whip out your health kit. There's plenty of wall arts, statues and structures along the streets that are worth taking pictures of. Most galleries would ask for admission fees. It'd be good to take a walk around when the weather is comfortable. There are a lot of coffee shops, snack houses and restaurants around. There are also a lot of shops and book stores. Some are unopened and/or abandoned. Unless you visit every gallery, you won't see much art. It is more of a commercial area
