Nicely appointed apartment in a great location. So much of the city is in walking distance. The lock code system was easy to use. Everything I needed was there. Sent a few notes to the hosts when I was dazed and confused and they responded quickly. Met the woman who I believe cleans the apartments. A very nice and helpful person. The front desk staff was also very nice.
Not the fault of the hosts, but the WiFi service was out two days out of five. The host contacted service who reported that there was a widespread outage in the area. A friend who was staying in another area was having the same issues. I have Verizon International, and that was not reliable. There is free reliable WiFi Service in Plaza de Armas, even when there is an outage in other areas. This might be helpful to know for someone who is working remotely.
The metro/subway system is easy to navigate and inexpensive. A great way to get around town.
