There aren't a ton of choices inside the walled city, but they are all charming and provide calming oasis from the bustle and heat of the city streets. The most important features to look for are pools and air conditioning, both of which are necessities in the heat as far as I'm concerned.
Super cool and boutique-y, it's less Cartagena and more high design but the pool, rooftop deck and restaurant (El Gobernador by Rausch) make it a great place to hang your hat.
CASA SAN AGUSTIN
Set in a former monastery, Casa San Agustin does a flawless job of maintaining its authenticity while providing 5-star service. Everything from the most comfortable beds on the planet to beautifully maintained gardens make it a total pleasure.
HOTEL SOFITEL LEGEND SANTA CLARA CARTAGENA
It's all about the pool here — it's the ;largest inside the walled city. In fact the entire hotel is larger than any other inside. Housed in former convent, the building is beautiful but the rooms definitely feel less authentic and more big box than some others.
