Guillermo Francella is an excellent actor both as a comedian and in drama. He has done other works such as "The secret in her eyes", along with Ricardo Darín, which is a drama about a dark period in the Argentinian political and social turmoil in the 70s and 80s. Also the very enjoyable "My masterpiece" along with Luis Brandoni, and many more works.
This story describes a very narcissistic man and, in my opinion, a classic psychopath. He is absolutely wicked. Everything he does is for his own benefit.
At the same time, we get to know the residents of the building. Some are very bad, but none reach the level of wickedness of this character. It is very funny and also a great study of personalities done in a very pleasant and entertaining way.
