We stayed over for three nights and it was overall a good experience, unfortunately tainted by a strong cockroach problem. On the first night we noticed a couple running around in the kitchen, we are not squeamish so we simply notified Julieta about it so she could take care of it in due time. She kindly offered to come and fumigate the flat but we really didn't want to go through the ordeal for only a couple of cucarachas. Then the last night, upon returning and having bought food to cook in, they started coming off from everywhere, of all sizes, a dozen or so.
We decided to get out again and eat out and notified Julieta, I hope she has now taken care of it.
Besides this accident ( and a really noisy next door neighbour on a Sunday late night) our stay was perfect. The "personale de seguridad" was absolutely lovely, the flat was neat, nice open view over the city, bright, Julieta was always very available. If the cucarachas are gone, definitely recommended!
