On the whole, my stay was fine but it was the little things that added up to form a not entirely pleasant experience. This was my first time Airbnbing and I was a little nervous staying with the people I didn't know. Maria and Carlos were fine, but i was not aware that this would be a hostel-like arrangement--there were 2 other people staying in a room across from mine. It worked out fine, but this was precisely the reason I didn't choose to stay in a hostel--I didn't want to be surrounded by strangers, and there was nothing in the info section of her place that pointed in that direction.
Another big issue for me was smoking. The hosts smoked at night and the smoke drifted right inside my room. Being a non-smoker, this seriously disturbed me.
When it came to using a bathroom, I found my things being constantly moved around although the hosts didn't specify exactly where I should keep them. This annoyed me and made me feel unwelcome. I accidentally left my skirt in the bathroom once and was told not to do that again because of the presence of the other guests, which made me feel totally weird. First, I didn't know that there were other guests, and second, things happen and there was no need for the host to lecture me. It was just a skirt after all, not gross stuff.
But the thing I appreciated least of all was my departure. As I gave Maria the key back, I asked her to come down with me to the front door and unlock it for me to let me out. She said something long that led me believe (my Spanish is very poor and she knew that) that the door is open. I specified my question again in extremely basic English, laying heavily on the words "door" and "key," and again, she nodded and led me believe that it should be fine. We'll, it wasn't. I couldn't get out of the building and was stuck in the space that separated the inside from the outside. My phone was dead, so I was buzzing other people's apartments (hers wasn't amongst the other tenants') to let me out at 8 am. This really got me mad as I felt that she just didn't want to bother with me anymore since I was leaving and therefore was used up material.
