This is a small and basic but clean and super conveniently located attic apartment. I think it represents good value for the price (much cheaper than other options in Prague). There were many non-touristy food and drink options within close walking distance, including 2 supermarkets if you want to cook at home. We appreciated being able to reach and explore the Old Town on foot without being in the middle of it. There are also excellent transport links to the station and other parts of the city outside the door (tram) and < 5mins walk (metro).
Small con is that it is noisy even at night (especially in summer with the windows open), so take ear plugs if you are a light sleeper.
We didn't meet our host, Anna, but she was kind and very responsive, solving a small problem with bedding quickly and positively.
