Extracting information from a real estate description

Hi, I would like to use/train a model that extracts a certain type of information from a real estate description:

for example terrace surface area:

input: This large apartment has a big south-east oriented 10m² terrace with a nice view.
output: 10

The goal is to use it on 100k real estate descriptions.

What model or type of model do you guys recommend for tasks like this?
