Valerie's place was great for a 5 day trip to the heart of Prague. so conveniently located literally a block from old town square and within 5-10 min of most bars and restaurants. noise isolation from the street was good, and there is central air. the building and neighborhood also felt very safe.
Valerie was a great host and responded to messages promptly. do keep in mind that there is a cash tourism surcharge and a fee for early check in (even just to leave bags)
the space was large and accomodated 5 people well. there were some basic necessities provided, although very bare. the washing machine was very small and took a long time to use, and there is no dryer, however there are ample drier racks to use.
overall I'd highly recommend this place for an affordable stay in Prague!
