  Fast Radio Bursts (FRBs) are extremely luminous and brief signals (with
duration of milliseconds or even shorter) of extragalactic origin. Despite the
fact that hundreds of FRBs have been discovered to date, their nature still
remains unclear. Precise localizations of FRBs can unveil their host galaxies
and local environments -- and thus shed light on the physical processes that
led to the burst production. However, this has only been achieved for a few
FRBs to date. The European VLBI Network (EVN) is currently the only instrument
capable of localizing FRBs down to the milliarcsecond level. This level of
precision was critical to associate the first localized FRB, 20121102A, to a
star-forming region in a low-metallicity dwarf galaxy and physically related it
to a compact persistent radio source. Analogously, a second repeating FRB,
20180916B, was found to just outside the edge of a prominent star-forming
region of a nearby spiral galaxy. The PRECISE project (Pinpointing REpeating
ChIme Sources with EVN dishes), starting from 2019, has observed hundreds of
hours per year with a subset of EVN telescopes with the goal of localizing
repeating FRBs discovered by the CHIME/FRB Collaboration. The ultimate goal of
PRECISE is to disentangling the environments where FRBs can be produced. Here
we present the state of the art of the FRB field, the PRECISE project, and the
localizations achieved until now, which have unveiled a variety of environments
where FRBs can be found that challenges the current models.
