Ushguli is a city in Svaneti.
This place is ten times more beautiful then Mestia. There are four to five villages next to a mountain.
Transportation into Ushguli is very limited. There is a road from Kutaisi that is serviced by private vehicles. Otherwise a trip from Mestia is the easiest way to see Ushguli. A private vehicle can take you up for a day trip, or for a few days. The cost will be ~$50-$70 USD for a day trip. The cost would be longer if you stay a while longer. The trip from Mestia takes about 4-5 hours despite being less than 70km in distance due to the poor quality of the road. It is also possible to hike from Mestia in 3-4 days which is a great way to see Svaneti for the able-bodied.
Once in the villages, you can walk between them all very easily.
A visit to the Ethnography museum is well worth the GEL 5-6 that the local children will ask for admission. Housed in a preserved Svan house, the museum contains artifacts ranging in age from the long history of the Svaneti regions. The local children will provide rehearsed description of the artifacts in passable English.
The Georgian wartime treasury. Placed in the "most inaccessible part of Georgia" the countless national treasures were held in the Ushguli monastery during periods of conflict.
There are a few cafes, and stores. You could also get food from your guest house.
Ask anyone in the village for a place to sleep. The price will be $20-$30 per night and include all your food.
You need to hire a private taxi.
