Safety is generally not a problem in the busier, more touristy parts of Morocco. As said, if you stop to look at all the wonders of the souks you will be greeted by overzealous traders frantically trying to help you part with your money.
Marrakech has the problem of pick-pockets but apart from the there are no serious crimes.
Moroccans can be very friendly and helpful but occasionally they may want payment for taking you somewhere or even giving you basic information if they see you are curious.
If you plan on staying in Morocco then travelling around is easy with either taxis, where you have to agree on a price if travelling some disatance, or by bus or coach to somewhere like Essaouira on the coast.
There is so much to say about Morocco but then we do not know what specifically your interests are or how long you will be staying.

Ivan,

In general Morocco is an extremely safe and hospitable country. Marrakech is a wonderful city with a lot to offer the traveller. My advice if you are alone is to hire a guide for the day (or even 2 or 3 days). This way you will get to see as much as possible in a short amount of time. Of course, they will take you to shops where they get a commission but everyone is entitled to make a little bit aren't they.

Stop worrying and enjoy your visit to the Magrehb!!

Sofree - the best time to visit Morocco for cooler weather is October/November and again in March/April/May. But your friend should be able to advise you on the best times. You can use your credit cards in the bigger cities but for the most part "cash is king" and you'll get better deals with cash. I have no idea on the costs of rental houses for a few days. the amount of money you take is hard to guess at - if you are also going to Ghana why not allow yourself US$100 per day (or is that not within your budget?). This way you will be covered for everything including emergencies.

Ignore the negative comments about travelling alone. getting about is easy and there are many wonderful sights to see however you'll be hassled by guides and traders alike.
Many women go to Morocco alone and have a great time; wherever you go you will find men leering at you, this happens all the time so you just need to be aware of this and use common sense.
Unles you are naturally flirtateous, ignore politely the advances of all males, they will have different resons for chatting you up.
The main problem will be of language; if you speak French then this will help immensely although having said this, some taxi drivers do not even speak this.
In restaurants, hotels, shops etc English will be spoken widely but not necessarilly to converstional standard.
