Location was wonderful as it was within walking distance to some great places in the NQ, great communication on the host's part and the check in was very easy and accessible. However, I must say there are a couple of things to reproach for... The linens were a bit stained - blood or something else - and we found some old food in the microwave (it was moldy).
Keep it in the back of your head that you will pay for the closeness to the centre and it's good for what it is. Maybe ask host to make sure fresh linens are there and that the appartement is indeed clean.
