Pros:
Good price, beautiful apartment, centrally located, sufficient amenities and quick response from the host when your experience issues with the apartment.
Cons:
Difficult check in process (you have to be tech savvy and very patient), very noisy (loads of noise from the street due to the central location as well as noise from the people staying above/neighbours), issues with the AC (in Spanish heatwave this is critical), the location is on a dodgy side street which is uncomfortable for girls coming home at night and many issues in general with the apartment.
Overall: it was okay for the price but we would not use this provider/host again.
