Imant was a great host, we had no problems with the communication or keys and could even store our luggage for half a day at his office. The location is perfect for a city trip in Rīga - Old town and everything in walking distance.
The apartment was nice, unfortunately there wasn't any real sitting area as the third bed was in the kitchen. As there is a hostel right next door it was absolutely loud all night and I could hardly sleep even with a closed window.
The bathroom was a bit shabby and we didn't have any spare toilet paper, but the beds were nice and comfy.
If you are planning to have a party weekend in Rīga or don't care about noises, this place is perfect from location and comfort :)
