There was quick response from the host, good communication on the day of the arrival although we were surprised to find out the location of the flat - within a hostel.
The flat was clean unfortunately there was a stale smell of cigarettes coming from the toilet which was unpleasant. We did report it to the reception and hopefully it has been sorted.
Otherwise the flat is located in the heart of Riga - the Old Town. It is good for a short stay.
