The apartment was large and conveniently in the hub of trams and metros and even fairly close to the train. We were able to get downtown quickly, and even to the the main castle area with a single tram. We also walked to town and back quite often, it's an easy 15-30 minute walk depending to where in the old town. We were grateful for the elevator up to the 5th floor.
Jarka & Maury were always very communicative and helpful, including in recovering our airplane lost baggage even though the delivery service was difficult to deal with.
We also asked for an umbrella and he showed up in 15 minutes with one in hand, and offered good ideas for spots to visit.
The area is safe and friendly (all of Prague seems to be). We found a BioMarket (thanks to our hosts) and it had gluten free bread and other goodies we needed. This and a pharmacy, drugstore, and grocery store are all within 5 minutes walk. There are street level restaurants we heard a bit but although we are sensitive to noise it was usually not a big deal.
We were happy we selected this apartment as it easily met all our needs and the hosts were so great.
