We stayed at Cristina's place long term for 1 month during the middle of the summer. Our check-in went smooth and she is a friendly host, but we had many problems during our stay.
The place is old and poorly maintained. It is not worth the price:
The kitchen sink was clogged with food and the water wouldn't drain. The air conditioning was only strong enough to cool down the living/dining area. It doesn't reach the kitchen or the bedrooms. We spent weeks sweating in bed trying to sleep. There was one small fan provided and we requested another one that we were able to receive a couple weeks into our stay.
We had internet problems (due to an old modem) which Cristina did help resolve as quick as possible - thank you!
The bathroom ceiling was falling apart due to a the apartment above leaking water down. There were building materials constantly falling into the bathroom and bathtub and water dripping from the ceiling.
The washing machine doesn't work well. It just wets the clothes.
