We visited the Biennale and were guests in Paulina's apartment for three days. The communication with Paulina was perfect and she documented us in advance about the apartment and how to find it.
The apartment itself is very well located, and is in a quiet residential area. Both the Giardini and the Arsenale can be reached in a few minutes. The accommodation costs were quite expensive, but the stay is worthwhile in any case. We felt very comfortable in this extraordinarily well designed, sophisticated and well equipped apartment. We especially appreciated the underfloor heating, as it is already quite cold in November. The only negative point were the mosquitoes that stole our sleep (although we only opened the windows for a short time to open the shutters). So take a mosquito spray with you.
In any case we will come back in two years at the next Biennale.
