Kristina was very good with communication! Wifi worked well and everything went as we hoped. The walking to the Prague 1 area (main touristy area) is not bad, only about 20 minutes or so but tram is very close by and comes very often so I would recommend using the trams! Overall, I would definitely recommend staying in Prague at Kristina's place. She will answer any question you have regarding Prague. :) Oh only thing I would say is, keys for the doors were not easy to use for someone who came from the US but it seems like all the keys seem to work the same way in Prague (not specifically only Kristin'a place).
