We stayed at Nicola's flat for a week in October. The flat is lovely, airy, calm and well equipped. Its location makes it very convenient to visit San Telmo, the ecological reserve of Puerto Maduro or the shopping district on foot, and other areas of Buenos Aires can be reached by bus or subte. The flat is well equipped, and has plenty of little homey touches. Being able to do some laundry was also very convenient.
The main problem during our stay was that there was no wi-fi for the whole duration. We never managed to solve the problem and lost quite a lot of time trying to figure out alternatives. Despite this, we had very good communication with our host, who did all she could do from a distance. Also, Nicola's wonderful neighbour and friend Jenny opened her wifi to us to partly mitigate the issue, and she was also a mine of information and good spirits.
