Although I didn't get to personally meet Catalina & Antonio, communication was very easy and they were very, very helpful. The location of the flat makes it very easy to get around. You are within a 5-10 minute walk to the metro and Tram 28, about a 15 minute walk to Miradouro da Senhora do Monte (which is a MUST at sunset!), and airport access is extremely easy (about 20 minutes by taxi or 45 minutes by metro - both are cheap). The flat is very clean, the bed and pillows are comfortable, the wi-fi is strong, and there are English speaking channels on the television (including cartoon channels if you have kids). I definitely recommend.
