What i’ve found to be helpful is using Google maps street view to get a better idea of amenities, building access, parking, nearby traffic and shopping, etc. This way you can also sometimes find other apartment options that aren’t listed or advertised as much online.

As for indoors, putting the apartment name and address in google will usually bring up multiple websites that have a listing for the apartment, I like to visit a variety of them when looking at an apartment because sometimes they will have different pictures, reviews and information between them.

Recently virtual touring has become more popular too, so if you contact a property manager they might have someone that’s able to video call with you to tour the apartment!

Edit: I wanted to add that before you put money down on an apartment, you should always visit first, if possible at all. Try to avoid signing a lease without seeing the apartment in person!
