We had a short stay at Viviana's place but it was quite pleasant. The location was quite central. It was close to the metro and there were good places to eat nearby. Vivana clearly stated all necessary instructions regarding check-in and check-out and responded quickly to all our messages. Since we were leaving at a late hour after check out, she arranged a place where we could put our luggage, so we could explore the city comfortably. The room we stayed in was small but adequate for a short stay for two people.
