We had a really pleasant stay in David's apartment. We were there for just over a month with our 10 year old. The apartment was very clean. Sheets are nice, towels in good shape, etc. The building felt very safe. There's always a concierge and cameras all around. It's super central which is very convenient but also quite noisy. Having said that, the noise never kept us up at night. We loved sitting on the balcony and enjoying the view. Despite being there during the civil unrest, Plaza de Armas was always fairly calm with families hanging out in the evening.
