Our Experience in Prague

Accommodation - Air BnB.
Our host Michal was very accommodating especially as we arrived an hour and a half later than planned. He was also helpful and explained the apartment details fully. 

The appliances worked well and the shower was very nice. 

There were a few issues as we were to discover: some of the lights did not work, a couple of outlets were non-functioning, the outside noise could be distracting for some (fortunately it didn't bother us too much), and there were a couple of unstable slider doors that rendered that space unusable. Also the wifi was extremely slow. 

Food.
We used a nearby Tesco market for groceries but ended up eating at home only once. Our neighborhood was packed with great dining venues. We can strongly recommend Pilsnerka Narodni, Monarch and Pho Bar.

Public Transport. A big thumbs up for Prague on transport. First off all trams, busses and the metro are free for seniors (65+) with proof of age. Second, the trams go everywhere and are easy to find and use. 

The metro was fast, smooth and a great way to cross the city quickly; also it was nearly all esclalators and elevators.

Our one experience with Uber was OK but we opted to rely on the tram system which was extensive and for us (over 65) free.

Attractions. 
There is plenty to see and do in Prague but you knew this already. The Charles Bridge, the Jewish quarter and especially the old Cemetery (a feee to enter), and of course the Prague Castle. 

We were a bit disappointed in the complexity of the various ticketing systems: rather than an attraction with multiple elements (such as the Jewish quarter or the Castle) having just one ticket you're required to pick and choose the various elements you want to see and then find the right bundle. Quite awkward. 

Communication.
No landline phone so relying on mobile is the only option. A smartphone is a big plus for texting and occasionally checking maps. It's also possible to get tickets to some attractions right on your phone..

Currency.
You can use euros with confidence but we found taking local currency out of a bank ATM (NOT     Euronet) worked well. While many places take credit cards it's always nice having local currency on hand for incidentals (ice cream, the odd aperitif, tipping). Note that Prague is quite inexpensive.

Masking and vaccination.
Neither seemed to be an issue. No one asked for proof of vaccination let alone booster and masking mandates were gone, left to the individual's preference.
