Love love love this apartment! We stayed for 7 days in Recoleta and its central to the rest of the city and the subway. The apartment builidng is safe and secure, the staff is helpful and accommodating. The apartment itself had a great kitchen and tools for cooking, a comfortable bed and couch, a great balcony view. The sauna was really nice too, the pool a bit cold but probably because the time of year.
Definitely recommend staying here for your holiday!
