I can't understand if this tiny board can work standalone or if an external microcontroller is mandatory.
Could I just store a tiny webpage in internal memory to get sensors reading from remote?

Not sure why nobody relied to you but yes, this module can run by itself as a webserver. There are plenty of examples on the internet. Flashing NodeMCU is a good place to start.

It is working very well standalone, native SDK thru Eclipse, LUA / NodeMCU.
With NodeMCU will be very easy to start exploring ESP8266 capabilities.

For more informations about you can take a look here:

It is working even directly from Arduino IDE (still experimental phase yet):
