The flat is very nice, clean, in the center of Porto and well equiped (even if we didn't had the toaster) but VERY NOISY : you can hear what is happening in the corridor and on the neighbourg's apartment but the worst is that you hear everything from the street and there is a lot of traffic, almost all night long (buses, trucks and cars)
Even very tired we didn't slept well, even with earplugs (and i m used to live in the city center of Paris)
We didn't met Dalila but she replied quickly to our request by email and flexible about our arrival and departure time.
