Katerina’s place is good. It’s a great location - residential but you can walk to the castle and bridge in 20 minutes through a beautiful park. The 26 tram and others take you wherever you need to go as well. Very efficient and great tram system in Prague! The place is spacious and would be perfect for 1-3 people. Comfortable bed and all the things you need like morning coffee and tea. The only downside for me was it could have been a bit cleaner. Granted my standards for cleanliness are pretty high - this was not a huge concern.
Overall it was a great stay with a gracious host who helped me transfer to another place she rents nearby for an extra night. Kateřina is a very kind and lovely lady! Thank you!
