I stayed at Jev's flat with 9 friends for a weekend. Communicating with Jev, as well as checking in, was easy and straightforward. He was flexible with our check-in and check-out times, and he made sure everything was ready and neat.
Jev's place is located in a calm area 20 minutes on foot from the city centre. There are some restaurants around but not much else. The flat is spacious and has anything you need in order to have a pleasant stay.
I definitely recommend staying at Jev's place if you visit the lovely town of Riga.
