we stayed in Alexandra place for 3 nights. The communication with her was mega smooth. The location of the apartment is fantastic, beautiful restaurants down the house and bars in the parallel street.
We found everything we need in the apartment, even being welcomed with typical Portuguese cheese and drinks was very thoughtful.
The only little problem is the stairs in case you have a huge luggage but it is the case in all buildings in the bairo alto so you won't be able to skip this.
The apartment was very clean, very nice decorated and it looks exactly like the photos.
I really recommend it.
