Apartments are simple but good. All amenities are available, it's clean, the location is good... apparently all one could wish for. There is however a major downside.
On fridays and saturdays many young people from the countryside come to Tallinn to have a party. And these apartments seem to be a very attractive location for them to do so. Since the apartments are very empty and hollow and the walls wafer-thin you'll be able to enjoy every party, all night long. Complaining to management won't do you much good; although they try to find solutions for you they never once consider ending the parties, which go on all night.
So bring your earplugs or go elsewhere!
