I had an ok stay at Carmen's. There are a few pros and cons so I'm going to mention it all to be fair.
Pros: Its clean, looks exactly like the pictures, communication is fast and Carmen did let me check in and hour earlier. She wants you to communicate via what's app and I preferred to communicate via the airbnb app. This is because it's easier since I'm just learning Spanish and also it's an advise from Airbnb itself. Carmen did switch but I don't think she was very pleased with me since she asked me use to google translate to understand what she says in what's app.
Cons: I stayed here end of November and the apartment was cold at night. When I asked Carmen for a heater this is how she responded " No one has ever asked me for one in 3 years" I was every suprised to hear that. She said she will bring me one but I never heard back so I just had to use multiple blankets!
There are many rules to stay here like no shower more than 5 minutes!
How I felt like staying here was like staying at a hostel but a much more expensive one!
The place is also about 20-25 minutes from the centre and not 15 minutes.
