Sandrine's place is well situated near the santa apolonia train/metro station and just a few minutes walk from the heart of alfama. We stayed there during the sardine festival whose music and festivities on the street were excellent and lively yet unheard in the secluded cul de sac where the apartment is located. The location is therefore great and the apartment calm at night, although if one wants to sleep in past 10, the occasional children playing/shouting or dog barking can be easily heard inside the apartment.
Sandrine was quick to respond and available through messages. While we met her friend Andreas, who greeted us and welcomed us with a bottle of Portuguese wine and offered suggestions to good restaurants in the area which we greatly enjoyed and appreciated.
We would definitely recommend this place as it was a great value in a great location.
