Careful with your reservation - we selected check in time at 9-11am and our reservation was accepted but clearly it was either an automatic acceptance or whoever accepted it didn't check the information. we arrived before 11 to find that the apartment was not available and would not be available until 3pm. The administrator was unhelpful and did not even bother to apologize for the issue.
Other than that, you get what you pay for. The location is nice, the apartment is good enough to spend the night and not much more - it has no main (eg ceiling) lights and is only lit by a few lamps, so it's not possible to do anything that requires more than a minimum of illumination. The wifi is not great, and there was also a pile of dirty clothes inside the closet (probably from a previous guest?)
