Excellent apartment right in the centre of Riga. Very calm, has everything you need to live and even to work. Cafes/shops/boulangeries/book shops/art spaces are nearby. 5 min walk to the railway station - it's so cool when even if you oversleep and then have to run to the train, you hardly miss it.
Communication is amazing and rapid, and checkin (as well as checkout) is comfortable - my departure was at the late night.
