Your Philodendron will be happiest in a space will lots of natural light, but out of direct sunlight. Their leaves are quite delicate and will burn if exposed to too much direct and harsh sunlight
There are a couple of types of heart-leaf philodendrons. Var. oxycardium has new leaves that are glossy and brown and var. scandens has new leaves that are light green in colour. There are some variegated varieties out there too which are sometimes mistaken for Philodendron but may actually be a type of Pothos.
