We spent NYE at Cartagena (5 nights) and were very pleased with our overall experience at Casa Pestagua. We actually discussed if we should rate it 4 ou 5 stars on Tripadvisor. We agree with previous comments but there where a few minor glitches, not even worth mentioning, and in our opinion Casa Pestagua would earn 4 stars if compared to top notch European Boutique Hotels (as we have stayed) but it deserves 5 stars considering this is Colombia and, specially, considering it probably has the best location in Cartagena - situated near most main attractions, including night venues (easy walks at night). At the same time once you step in, peace and quiet rules. This is an Oasis on a crowded and fun part of the city.
Big rooms, cosy and relaxing breakfasts, excellent Spa treatments, nice swimming pool to escape the mid-day hot weather (could be better cleaned and bring you insect repellant to the pool area in the afternoon), and we were happy to ask for the Hotel driver to take us to the airport, almost the same price but much more confort than a normal taxi.
There are areas that could be improved, but again, the fifth start is well deserved due to its location.
