Apartment is in an excellent location, short walk to the old town and great transport links nearby (minutes to Riga train station).
Apartment itself might be slightly small for some couples, but the location definitely makes up for it.
Washer is provided but do bring your own laundry soap.
Overall a great apartment and excellent hospitality from the host, but i would caution those with a fear of insects as there were many drain files in the building itself and also in the apartment. Do note that there is no elevator in the building (apartment is on the third floor).
