As we arrived really late, Tomass offered to get us at the aiport for a modest price. He was really nice and there was no problem with the late check-in.
The flat is well located within a walking distance of the Old Town of Riga and next to the Chocolate Museum.
The flat itself is a bit dark but comes with a big kitchen and a Smart-TV. There was a bit of mold in the bathroom which has no window but, overall, the flat was clean.
All in all, we had a nice stay in Riga and I recommend this Airbnb due to its location and nice host.
