Hello Harold, how are you?
It's very easy to rent an apartment in general but somehow difficult for 3 months of rent but renting for a year or so would be much easier.
Regarding tax, you pay nothing my friend. There are some small taxes like city cleaning and things like that, that you pay when paying the water bill.
But except these payments, there is no tax.
Also, when you rent an apartment 99% of the time utilities are excluded from the cost.
Hope you do enjoy your stay in Albania
