First, I'd like to say the good things. This place is really nice! Having your private balcony is great, and the place is precisely as it looks in the pictures. It's perfect for a solo traveler or a couple.
My only issue was with the shower. Marta does give you specific instructions on how to operate it, but after 20min of fiddling with it and trying over and over, I just could not get it. I ended up having a cold water shower for the entire stay I was there. Plus the water pressure is not great, even at full blast.
The WiFi did go out two days before I left, but it wasn't Marta's fault. The company itself was having issues, but Marta was very ambitious to try and fix it. She even offered me a local SIM to use for hotspot until the WiFi came back. I should mention though, even when it's there, it's very shaky and it's only good for the most basic tasks.
Overall however, I did enjoy my stay. The neighborhood is very safe and quiet and I wouldn't mind coming back here! :)
