Don't get me wrong, But personally I do not see anything wrong with this thing/residence. At last this is the country's presidents official residence and where he may use to meet delegates, conduct meetings etc. And also he needs to set up an office inside the residence as his job is not a 9-5 type. Also any country, the first persons residence would have looked like this or more luxurious than this.
(of course I am not saying these all are ideal for a country like us - for example the amount of computers there - it needs good investigation- but apart from that computer thing, other set up "per se" you can not accuse)
Its a different thing to investigate the corruption and use of this place for election propagandas he did but this residence thing is bit silly I guess
