Vaclav's apartment is in a peaceful neighbourhood that's easy to get to from the old town and vice versa. The public transport gets you there quickly but the walk there is worth it as well as you get to see the many shops and sights along the way. We didn't meet Vaclav in person sadly as he was travelling but his responses were prompt and he was very accommodating regardless of not being around. We did however meet his mum who was lovely and her dog who was cute and friendly. The flat was clean, tidy, cosy and had all the necessary amenities as well as a clean bathroom. We thoroughly enjoyed our stay and highly recommend this air bnb to other travellers.
Word of advice. If you book a taxi, get some Czech currency out beforehand to save you hassle. Most of the atms charge a ridiculous withdrawal fee at the airport but there are a few that don't. We unfortunately didn't realise this and afterwards felt like we were robbed.
Also jen cafe just round the corner is a must for breakfast.
