Mabel organised a taxi driver to pick us up from the airport and waited for us to arrive. Her husband walked with us to shops and a bank in the neighbourhood the next morning, and informed us were to shop for groceries. They lend us a SUBE card to be recharged for use on the local transport system, which was very convenient. When the internet connection dropped out the next morning, after they had gone on a holiday, their son fixed the problem one hour after being notified. He accompanied us to the railway station on our last morning and even paid for our tickets to Retiro, as we had returned the SUBE card. We found Mabel and her family very friendly, helpful and accommodating. They are great hosts, and their son Flavio speaks English very well.
The apartment is spacious, comfortable and well heated.
