We were a group of 6 - a family of 5 and a family friend. the accommodation was ideal for us - plenty of space (one of our sons slept on a bed settee which was fine) and 2 bathrooms. The apartment is in a pleasant area - quiet - felt very safe -close to cafes and a supermarket withing a few minutes walk. Los Leones metro is nearby too and the river - we stood on the bridge here to watch the fireworks on New Years Eve. One day we walked to the providencia entrance of San Cristobel and caught the cable car to the top (quieter than the main entrance) and the funicular down into the centre. We walked from there to the main square and caught the Metro back.
Fulvio was always quick to respond to emails; he was helpful and friendly. We collected the keys from him at his office nearby. We would definitely stay here again and would recommend Fulvio's place.
