Isabel's place was fantastic. It was very centrally located, literally a 5-10 minute walk to most things. The apartment itself was great - roomy, clean, and safe. One thing to note (and this isn't hidden or anything, as other guests have mentioned it and we just didn't pay attention to it!) - getting to the apartment requires going up a lot of stairs or a lot of hills, if you're walking, so just be aware of that if you have heavy luggage!
Overall, I think the apartment and our experience with Isabel was even better than expected! Would definitely recommend :)
