The apartment is within walking distance of the port (I took the ferry from Helsinki).
The room was small, as expected. The only two things that were annoying was 1) The shower curtain should add weights to the bottom so that it hangs straight and provides more room when in the shower. 2) When accessing the loft, you do need to bend over in order to enter from the stairs. This apartment is not suited for elderly people.
The bed and room were comfortable. Fan was provided (nice). Microwave, Refrigerator, TV. Within walking distance of two grocery stores in the Old City.
One Complaint is with Expedia. They sent me a message the the Apartments did not have a front desk (NOT TRUE). During normal hours, the front desk always had a person available. Expedia told me that I had to contact the hotel 24 hours Tallinn, I was not sure if I was going to be able to access the apartment or not. Fortunately, Expedia caused me to worry for no reason.
If you don't have bad knees or are taller than 6' 2", I recommend the hotel.
