I had had a great experience in living in this apartment for three nights.
The owner is very nice, providing guilelines, support and suggestions on the travel in Tallinn.
The apartment is very clean and comfortable with many facilities, especially for cooking.
The location is excellent! It is in the city center. The main bus station and an international ferry pier are nearby. Supermarkets and shopping malls can be found too. Most importantly it is located near the Tallinn old town, which is very convenient for travel.
I would recommend this apartment for travellers.
