This place is, essentially, a hostel. The units are small, but clean, tastefully decorated, and complete.
The neighborhood may be a bit too close to the hustle and bustle for my blood. Service vehicles making racket in the mornings, drunks stumbling in the street below the terrace at night. It's safe, as far as I can tell, but I wouldn't recommend it to a woman traveling alone. This is no fault of the host, but it's something to consider.
