Even though I didn’t speak any Spanish, Mercedes was very friendly and accommodating to me. For example, she offered to wait for me until 1am for check-in and when I got held up, she left my key with the doorman and they knew to expect me. It was super convenient to have my own toilet and I felt safe going home late at night. It costed 100pesos ($2 usd right now) to uber to the obelisk and I felt the location was walkable to casa de mayo and Recoleta, though there were also lots of busstops and subte stations nearby.
