With a good location on avda de mayo in the centre of the city, Diego's apartment was perfect for what I needed.
The fridge, WiFi and aircon all worked well and there was plenty of hot water. I did not use the cooking facilities, so can't really comment - there was a double gas hob, kettle and toaster at the apartment.
The building has a security concierge and felt safe - although some peculiar banging noises late at night and early in the mornings. nothing to spoil your stay, though .
