The apartment is in a great location and would be a great place to stay if the host improved a couple of things. The bedding is threadbare and ill fitting and the pillows are very uncomfortable to sleep on. It these items were replaced it would make your stay a lot more comfortable. The coach is also split and uncomfortable to sit on.
The instructions for checkin. Issued the fact that apartment 27 is on the 6 floor and when you leave the lift you need to go through a glass door in front of you to find the apartment.
The apartment is a short walk to the old city and also the very beautiful Art Nouveau area. Riga is full of beautiful buildings and parks and is a lovely place to visit.
