Even though we only met once, Kristina and his friend were nice and welcoming. It took some last-minute room maintenance but only because I've arrived earlier than planned. The apartment is large enough for 2/3 ppl to stay and fully equipped (from towels to dishwasher). Perfectly located, close to lively riverside (perfect from 20 to 40 years-old) but not noisy at all, and quickly connected to the old city (some 5 tram stops to Charles Bridge or a 30 mins enjoyable walk). A tip is to get in bars and clubs in the neighbourhood if you want to meet locals and not to stuck in the center's tourist traps. I do recommend it!
