"No, no, no!" you scream at the screen in frustration, knuckles turning white as you grip the stem of your Chateau Baccarat glass.
"These properties simply will not do!"
Fear not, dear luxury lover, for the rise of the online sharing economy hasn't left you behind.
In recent years, several luxury-focused sites have been launched to allow owners of multi-million dollar properties an outlet to rent out their mansions, villas and penthouses to their wealthy counterparts for the short term. }}%

Output
Purpose
Flush text left and right without setting any tabs at every new line.
Maybe the tabs are setted because I*m using R Sweave and this formatting is used in that way. Using only text produces the same like \flushboth. But I tried flushboth to get the required solution.
Using flushleft works to clear the tabs but then the whole text is flushed left. Using flushleft and flushright does not work. You can use either flushleft or flushright. If you use both then that one which is closer to the text will be applied.

\parindentlength. Also,\smallis not a command that takes an argument, it should be used as{\small ...}, not\small{...}. – Torbjørn T. Dec 22 '15 at 13:59\flushboth{...}apparently as if with an argument (the same comment applies to\small) Latex Does not normally use the tab character at all (it treats it like a space) this code does not change the interpretation of tab so I can not guess what you meant by tabs being set or not set? – David Carlisle Dec 22 '15 at 17:46\parindent. – Torbjørn T.
