My overall experience at Anna's was good. I had some confusion regarding check-in, mostly because I hadn't seen a couple of messages that Anna had sent the night prior to my arrival. Even with those messages, though, I wasn't certain where exactly to find Anna's mom upon my arrival (Anna had asked that I text, which I didn't have access to), so I sat on the stoop outside the apartment building and waited, hoping we would run into each other. She came out of the building several minutes later, as part of cleaning up, and it was all smooth from there.
I will say I had a different impression of the location than what was reality. It was a solid 20 minute walk to old town (and I walk fast). Far enough away that I felt like when I departed old town, it was the end of my day. Trams were available, but the timing on that only worked for one ride. The neighborhood is working class with several gambling rooms and not exactly picturesque. It has a few good restaurants and shops within about 6-8 blocks, but is a little too far from the action for my taste.
I couldn't figure out if it was the plumbing or the water quality, but the bathroom - and the shower - had a foul smell throughout my 4-day stay. I know the Baltics are usually bitterly cold, but it was about 26 degrees during my stay - in May - so purchasing an air conditioner for the bedroom may not be a bad consideration for the sake of summer sleeping comfort.
Anna allowed me to drop my bags at her place, despite it being prior to check in, and called a taxi to the airport for me, both of which were very helpful and appreciated. Anna and her mom are great, but considering the priority I place on proximity, I would consider another location for a future stay in Riga.
