It depends what the question implies.
Did you mean a ship that is mine (read: I'm the captain) with a full crew? Then it would be probably a Sovereign class or an Akira Class, nice and comfy. A Prometheus Class would be fun too!
Did you mean a ship that is just for me, and thus that I should be able to manage alone (with just the help of the computer), than a nice customized Defiant Class, with an holodeck and some leisure space added instead of some of the crew quarters. If that is too expensive
, I'll go for a nice Danube Class runabout: those things are awesome if well configured, I can see them as space salon, more or less a good Audi A8 equivalent 
I'd kill for a Negh'var battlecruiser though... but let's stay into the Federation and stay pratical. Yeah, right!
