I went to Uzhhorod earlier this year. That's the spelling that seemed most useful online, though you may encounter others on various websites, including possibly variants beginning "Uj", which I think is the French approach.
I traveled to Ukraine on the ground from Hungary, which I had been visiting. Uzhhorod was my first overnight stop. I opted to spend the night in Debrecen in eastern Hungary (attractive place) so I wouldn't be so far from the border when I started out on the train the next day. From that direction, the quickest path seems to be the train from Debrecen to Zahony (Hungarian town near the border) then a small bus of some sort into Ukraine. I think the RR gauges are different in Hungary and Ukraine, and you may wait many hours in Zahony for a train to Chop. It's much faster to go outside and try to find a bus headed to Uzhhorod, or at least to Chop, where you can get a bus to Uzhhorod. You can expect some of those buses to look like rattletraps. Be sure you know what the possible city names look like in the local alphabet, though they may also be shown in ours (for the benefit of Hungarians); I don't remember.
If you have to change buses (vans) at Chop, it would be best (maybe mandatory) to have some Ukrainian currency to pay the second driver. I wandered off in search of an ATM, not having had the foresight to seek information online in advance, and I found one a couple of blocks away. It was the first of many Ukrainian ATMs that wanted to charge me a fee. In this situation, I didn't really have a choice, so I paid the fee. After that I allowed extra time to find ATMs that did not charge fees. (Be sure your bank knows you are traveling to Ukraine so it doesn't block your card.)
Uzhhorod is an attractive, though I would say not spectacular, place. You can certainly enjoy walking around for at least a few hours. Check TripAdvisor for local museums and other attractions. There's a nice walk along the river.
One of the challenges of smaller cities in Ukraine is the condition of the sidewalks. If you have a wheeled bag, you may be lifting it over obstacles quite often. I stayed at the Hotel Boutique which I recall as fine but not a boutique hotel by our standards. The hotel is a good walk (perhaps 3/4 mile) from the point where the bus dropped me off--most likely near the train station. This was the only small-city Ukrainian hotel that was able to give me a map of the city, for which I was grateful. I think the person on the desk spoke some English.
You'll definitely want to have a paper or electronic map in hand to find your way around, because you cannot assume that too many people will speak English. The second language in that area may be Hungarian.
My notes show that I had dinner at a place called A Priori, where I had chicken and grilled vegetables.
I enjoyed Ukraine a great deal. Aside from the aforementioned sidewalk situation, which is really only noticeable if you happen to be pulling a wheelie bag, there were three issues:
Ground transportation through the country is quite slow. There are lots of buses (comfortable between the really big cities, rather rough otherwise, as are some of the highways), which are often faster than the rare trains. The trains often run at very odd hours from the tourist's perspective.
The comfort stops used by inter-city buses have pit toilets. They are kept very clean, but if you're on a bus for 8 or 10 hours, that's a lot of pit toilets.
You will be hard-pressed to find a tourist office. I saw one (very helpful) in L'viv. I didn't find one in Kyiv (the capital of the country!) or Odesa, much less in Uzhhorod, Ivano-Frankivsk or Chernovtsi. So do enter the country with the information you need to decide how to spend your time and how to get around. Allow a lot of extra time when heading to a train station (probably no English spoken).
Otherwise, Ukraine was reasonably easy to visit.
