This is a very clean (aesthetically and in general) and spacious place that has everything you would need to stay for a day, a week or even a month (as we did before moving to our permanent apartment in Prague). The location was perfect for us, both in terms of entertainment and day-to-day needs. There's lots of little restaurants around, and you can also get anywhere in Prague by going to the nearest street and hopping on a tram or the subway. There's also a good grocery shop nearby, which was nice because we were staying for long.
Marketa is a great host, I can only say good things about our communication before and during the trip, I highly recommend staying at her apartment!
