This is a perfect stay for any solo travellers (especially female). The flat is in a safe neighbourhood that is extremely easy to reach via the Metro. The flat is basic but has everything you need for a comfortable stay (I was a big fan of how dark the room was at night).
Only things to be aware of is the walls are thin so you will hear people leaving early in the morning and there is only one shower for all guests.
Mariana was very accommodating with my arrival.
