This apartment is very well situated. The bus lines are close but we chose to walk everywhere and it was totally doable. The apartment is clean and comfortable. Everything worked which is always nice. We loved having a wash machine. We would just hang clothes to dry. Stepan gave us the suggestion to go to Savoy (around the corner) for breakfast- so we did three times. yummy. Make sure you check out the music scene. Not only street music -which was great - but go online and get tickets for concerts that are your thing. We like classical and went to a concert in the Mirror Chapel - probably heard the best female singer I will ever hear. Also the organist played on an organ ghat Mozart himself played on.
All in all a great trip. Prague is magnificent!
