Our host was very helpful leading up to our trip, providing transport and other useful information! The apartment was stunning and the location was useful for our travels. We were visiting a Prague local who said this apartment is far above normal city living standards and it was about a 25 minute walk from Old Town and other touristy areas.
Four people could sleep there, but three would be most comfortable, as the couch does not pull out. The wifi was definitely spotty but the other appliances were great, and we appreciated that he provided a hair dryer so we didn't have to pack that.
Overall, it was a great spot for us!
