The hotel is quite clean and per international standard, which is quite good for Abuja. The prices are through the roof though: internet access not included, meals are more expensive than in top notch Paris restaurants (and sub-standard), and a small bottle of water is 5USD.
Hotel says they offer an airport shuttle service (and make you sign a form committing to pay if you end up not using it), at the price of a taxi from downtown Paris to the airport - but no shuttle ever shows up. This happened to me and two colleagues (three days in row), despite complaining at reception. Better laugh about it.
Hotel will accept foreign currencies, but will not change your money.
If you don't mind getting ripped off, this is a good hotel to stay. But don't expect anything more than a good bed, at the price of a week's rent in London.
