I stayed here for a week and the stay was ok. There were positives and a few drawbacks: the positives include a safe location in town, 5-7 minute walk to the Metro, plenty of hot water and a good washing machine (but you do need to air dry) in the apartment. The communication was excellent - anytime I had a question I would get a prompt reply. The check-in was also very good as someone was waiting for me on my morning of arrival. Also you can order a Cabify just a block away next to a mini-market grocery store.
The size of the apartment is not huge but it was just me so it was fine. The major drawback for me was the main bed; it was not comfortable at all and I had back pain after the first 2 evenings. I switched to the sofa bed in the living room and then my back was fine for the last 5 nights. Everyone has different tastes as far as beds go but I was not a fan of the main bed. There were two smaller beds upstairs but I did not try them since the sofa bed ended up being ok. There was a bit of construction noise in the mornings (can wear earplugs to avoid this) and if I left the windows open flies would find their way in which was a bit annoying. But overall this was good value and provided a homely stay...the kitchen had plenty of amenities including a hot water machine and some basic supplies for cooking. There was soap and shampoo and plenty of clean towels and the building was just fine. The neighbors I encountered were very friendly.
