Romana's apartment was perfect.
It is ideally located. The city center is within walking distance and there are several streetcar and bus stops within minutes. There are bakeries, grocery stores, bars and restaurants nearby.
It has everything you need for a pleasant stay. It is spacious, ideal for four people. Access to the building and the apartment is by code, which is really convenient, and there is no risk of losing the key.
If you are a light sleeper and sleep with the windows open, the streetcar may wake you up. But with the windows closed, this is no longer a problem.
If we ever come back to Prague, we will definitely return to Romana's apartment.
