Sharpening with wet and dry sand paper and glass can be very effective. Getting transparent wood shavings suggests that the plane is quite sharp especially if you can do this with the plane "gliding" on wood without a lot of effort.
Rosewood is not the easiest wood to thickness and some of it is very hard. I would suggest you start a new thread about this topic
so more people will be able to make suggestions.
Working in an apartment suggests a number of things to be aware of. Wood dust is extremely bad for your health (even though sometimes the smell is nice) and anyone else in the apartment. You must get a good dust mask and you must clean up very thoroughly all the time. If you have a balcony do the dusty work there.
Working in an apartment, it may be difficult to have a very stable, very flat, surface to plane on. This could be one of the reasons why you are having difficulty with rosewood.
