I would just say communication was an issue. She very nice but should try and plan very very far in advance to organize arrival and key exchanges. Maria was nice enough to store our luggage and take us to the train station but the coordination was confusing and I felt like there was a language barrier in all communication. The apartment if you're there in the summer will require sleeping with the doors open. There was also a lack of towels and a broken shower head. The location isnt exactly ideal if you don't have transportation due to all the hills.
Overall the apartment was clean and cute.
