I am thinking of traveling solo (I am an older woman) in Moldova after finishing an organized tour in Romania. The first question is whether it is realistic to think of using Chisinau as a base for let's say five days and taking day trips from there to see the best of Moldova. I'm especially interested in art and architecture. Are there must-see sights that would be too far away for a day trip? Secondly, can anyone recommend Chisinau tour companies that would be reliable? About how much should I expect to pay for a full day with a guide? If I'm willing to forego the guide, how much might it cost to hire a car and driver or a taxi for the day?
