We had a lovely stay in Rui & Elsas apartment. The location was amazing- there were many lovely restaurants and cafes and lovely views just minutes from the apartment.
It was a hot weekend in Lisbon (30-35 degrees), so I would maybe choose a place with air conditioning next time- but everyting in the apartment was convenient and nice.
The communication with Rui & Elsa was easy and they answered our questions quickly :-)
