Tereza's apartment is ideally located for walking anywhere within the Old Town - about a 3 minute walk to the square. It was also very easy for us to get over the bridge to the Lettna Beer Garden (which we definitely recommend!) and eventually the Holesovice train station to head back to Vienna. We didn't spend a lot of time in the Jewish Quarter, but if you were keen to visit the synagogues, memorials and exhibits in the area, you're on the doorstep. The apartment itself is very spacious - there were 4 of us in the place and plenty of room. We were connected with a friend of Tereza's to do the actual check-in, and all went smoothly (and she arranged for us to get in a bit early so we could drop our bags before the walking tour, which we really appreciated.) overall, a lovely experience.
