I stayed at Eliana’s apartment for one month, and had a great time. The wifi was fast, the AC was cold, and the apartment was very clean. It was well stocked with everything I needed for the month, and the gas stove was great for cooking.
The neighborhood is more local and quiet than the center, which was nice for a month long stay. The city center is easily accessible by public transport. In the neighborhood you have everything you need within close waking distance including markets, restaurants, cafes, internet/print centers for printing documents and purchasing SIM cards etc.
Eliana was very responsive, easy to get ahold of, and provided great recommendations for sight seeing, restaurants, etc.
Only thing that I can fault is that there is a lack of natural light in the apartment, but as a result it usually stays pretty cool and is well insulated.
I would definitely recommend this place for any short or long stays.
