I visited Moldova last month for a total of 12 days. Overall I enjoyed it, though I like spending time in 'everyday life' not just seeing tourist attractions. I work about 4-5 hours/day (as a remote consultant/writer) and then look around where I'm at.
Chisinau: Did a free city walking tour (worthwhile). Visited museums: National Museum of Art, of History, City of Chisinau, National ethnography museum, Alexander Pushkin House, main cathedral. they have some nice parks and walked around the lake (near the university). The cathedral and central market. Visited the main train station and the surrounding open market. Tried to go on tour of Parliament, but no English tour when I was there, and the city bus tour was cancelled when I wanted to go. Food was so-so, but had a great Italian meal at a high-end restaurant near the US Embassy. There was a traditional culture festival that I attended
Went to Old Orhei, Balti, and Soroca (rented a car when leaving Chisinau). and then to the south, to Comrat and Cahul. Lots of farmland, vineyards. As stated, not a lot of traditional attractions, but I enjoyed just seeing daily life + leftovers from the Soviet periods. For getting around, I managed OK with just English, which was rather more prevalent in Chisinau than elsewhere not surprisingly. Also surprisingly, I only broke out Google Translate a few times.
Yes, this is inexpensive by USA standards. Prices seem to me about like Chile or slightly less, but a bit more expensive than Peru. My metric is ice cream. I had an ice cream cone in Cathedral Park, smack in the center of Chisinau, for $1.50. About the same as Romania and Georgia. I think I've paid like about $3 in Munich. In the US, you can pay as much as $9 for the same--yes the US has become so expensive. (the only expensive thing I experienced in Moldova was fuel for the car -- about $6/gallon.
I had a good experience, but I acknowledge this is not a visit for everyone.
