Nice apartment, where you will have one of 3 private rooms. You share the bathroom & kitchen with the other guests, please consider that! Wasn't a problem for us, if everybody is careful and looks out for the others as well. :)
Perfect location, you will be in the Old Town, but also it can get noisy when the clubs/restaurants beneath the apartment are open and play music at night.
After all a very good place to stay and explore Riga!
