Hi SaudiUk; depends what is your budget and where exactly you need to move around during day time for your official work etc. There are alot of options from 7 star Sarena, 5 Star Marriot, 3 Star Islamabad Hotel, and then medium budget guest houses.
NewCape has constantly maintained its ranking as top hotel guest house in islamabad at tripadvisor. Perhaps you should consult them for availability. I stayed with them and had a pleasant stay. What you see is what you get and the service is amazing. Owner's attention to every detail is given. Recommended accommodation to stay in Islamabad. (moderated: no ads please)
You can also check Fortellice in F-7 Islamabad. Its quite neat and service is also good. Else, its located in one of the most posh localities of islamabad and considered quite safe for foriengers. Good luck
An accommodation facility guest house in islamabad providing executive living for occupants looking to stay for longer duration has recently been started... Checkout their website roomsislamabad.com for room pictures and further details or send an email to them at roomsislamabad@gmail.com
