This studio lacks everything you might like about airbnb but the price. it feels pretty much like having a room in hotel - where it would cost at least three times the price you pay here. the standard is remarkable!
however, alex' apartment is impersonal and his policy is strict. for example, due to a delayed train, we arrived ten minutes after eight o'clock and had to pay a "late arrival fee" of 20 euros.
you must know for yourself if you want to stay at one of alex' studios. we enjoyed our time there but it left a shallow feeling of supporting someone who has made a big business out of renting apartments in prag via airbnb.
