The apartment is beautiful and colorful. A bit smaller than the pictures but with everything one would need for a stay of a couple of weeks.
I wouldn't recommend super long stays until the construction next door is finished (as of May 2022 it was 50% finished). I do also think that the apartment needs to be better taken care of to go the distance and offer a quality stay that can justify the cost.
I shortened my stay because I found a better place in the same neighborhood. I definitely recommend San Telmo, it's residential and with so many hidden gems.
