The central star of planetary nebula LoTr5 has recently become one of the longest orbital period binary central stars with the discovery of a companion at about 2700 days. The system, consisting on a rapidly rotating giant G star and a hot source responsible for the ionization of the bipolar nebula around it, still offers many open questions. One of them is the possibility of a third companion, close to the giant star. Besides, the spectra show a complex double-peak Halpha profile which varies with very short time scales. This could be mainly due to either chromospheric activity or the presence of an accretion disk. I will present our current knowledge of this interesting object based on different observations and how they help us to unveil the architecture of the system.
