I stayed at Florencia's place last week with my boyfriend and I just have good comments.
The location is really nice, close to metro stations, with lots of supermarkets, restaurants and cafes nearby.
The apartament is just as the pictures. Very nice and clean with everything you need, fully equiped kitchen.
Flor and her husband was very nice guests, providing us with maps, city guides and metro card, that made our stay much easier.
Overall, just loved the place and sure would go back ;)
