We never met Elsa and Rui.
We did meet Maria and she was very welcoming and friendly. She took the time to show us around the apartment. The communication with Elsa & Rui and Maria went very easy, they responded in no time to messages.
Apartment was really clean, the bedrooms, especially the double one, are nicely styled and decorated. Coffee machine in the kitchen is a real plus and if you stay for longer, there is a nice terrace to have breakfast or sit and relax. Only piece of comment is the smell in the bathroom and noise of the tram (I'm a light sleeper, the noise is not extreme) since the bedrooms are at the street side.
