Great location in central Riga, at the top of what is probably the "main" street in the old town (towards the river). Since old town is so small, the exact location within it is not that important, but what was most striking about this place was the spacious and modern interior of the apartment (it seems to be new or near-new furnishings). I didn't find there was noise at night (that's sometimes a problem in old town due to the bars staying open late). Communication with host was clear and easy.
Wifi was good.
Suggestions: a microwave is useful (didn't have this but had everything else, and good quality).
