We had a great stay at Carmen's place. Her apartment is really nice decorated and the room is something special and different to common hotel rooms. The bathroom is open to the sleeping room so you'll be able to watch your partner having a shower (which you should be aware off if you don't want your travel partner to see you while your on the toilet...).
Anyway the room was really clean and Carmen did everything to make our stay a good one: she provided us with all the information we needed also if it was sometimes quiet difficult as she hardly speaks any English but we were always able to understand each other.
Also Carmen's place is conveniently located 5-10min away from the subway station which takes you to the central part of the city. The area around the apartment is quiet and safe with some little coffee shops and convenient stores just a few minutes away.
All in all we enjoyed our stay at Carmen's place and we would always recommend it to our fellow travelers :)
