great value for money - go ahead and book, especially if you are a solo traveller. maria knows how to host well; she had many local tips and even helped me plan my route the next day. the famous bridge really IS just 5 minutes away; location couldn't be better. and unlike most airbnbs these days, maria's place feels like a home. just note as a general point when travelling, don't get scammed by street scammers! one approached me in the coach station and scammed me out of 20euros. he was very professional - looked really smart in a blue jacket, told me he had shut his exchange shop for the day (pointing to an exchange shop with the shutters down), but had some cash with him that he could exchange with me (i was staring confused at the ATM at the time). maybe you are not as naive as me, but this guy was a real con artist and had clearly performed this gig many times before. in general, prague seems pretty card-friendly, so you can purchase your uBahn/underground ticket by card, go dump your big backpack so you look less like a traveller, and then go in search of cash!
