This is a very nice space - comfortable beds, balcony, secured gate, stove/oven/microwave, dishes, shower, etc. It was very nice for a short term stay, but has everything you'd need for a long term stay except for a washing machine.
The hosts are extremely friendly and willing to help - they helped us with our bags, provided advice, and so forth. Since I speak limited Spanish, she would use airbnb's autotranslation feature when I didn't understand something, which worked well.
The only potentially bad thing is the stairs, which reminded me of a fire escape, that lead to the front door, while inside the apartment the halls are narrow and have single step bumps. If you're comfortable walking around on your feet like myself then you'll be fine, but it could be problematic for a mobility impaired person.
