Good location if you want to stay in Barrio Alto, near everything there but not in one of those too crowded blocks. Also great communication and check-in process.
But have in mind that this is a place to sleep, do not rent if you need to work or do something with a computer, since there is no living room and the kitchen is uncomfortable for that kind of task (poor wifi there and small stools in a tall kitchen counter, not even a chair or stool with enough height).
