Ilmars' place is a great value! Our group of nine drove down from Tallinn for a conference, and the flat was perfect for us! It's within walking distance of Old Town. There are plenty of restaurants nearby if you want to go out to eat. But there's also a kitchen and a Rimi across the street, so cooking is pretty convenient, too.
If you're looking for a no-frills flat in a good location for a group of people, I recommend Ilmars' place!
