As an Airbnb host in the states, Martins place is a dream come true. excellent location, all the basics in a modern condo style, and at an amazing value for price. highly recommend.
also for those foreigners like myself looking for a SIM card, after trying 6 stores, I found the one that does sell them. make sure to have at least 100 pesos and your passport. they are very friendly and will help you.
it is the Claro located on Av. Santa Fe 4420.
about a 15 min walk.
