Remember when you are booking this room that it is in fact a hostel. This means you can't expect a 5-star experience or amenities. You get what you pay for.
With that said, I do want to call out some things that many travelers may have issues with:
1. All rooms face one of two VERY busy streets. There is honking all night long. My partner and I thought this wouldn't be an issue, but falling asleep was often hard. There was also construction either down our hall or in the building most days starting as early as 9 am.
2. This is not the nicest area. While you are close to Centro Historico, you will definitely want to Uber home most nights, as the area does get a bit dodgier.
3. The restaurant in the lobby is good, but not great for the value. The service is extremely slow (the guys behind the bar don't really seem to care for efficiency), and the food is pretty meh. They also kept charging us differently depending on the day (sometimes charged extra for avocado, sometimes extra for milk in our coffee!). But it's really your only option for anything close by that isn't street food. If we were staying in a different area, we would've definitely gone somewhere else for breakfast every day.
4. We needed to change rooms because there was no safe in the room we initially got - make sure you have this upon arrival to ensure your belongings are safe (we felt the hostel was very safe the entire time, but you never know).
5. If your flight arrives early, just book an extra night if you want to get you your room before 3 pm. We ended up getting charged TWICE as much as one night for early check-in when we arrived (even though they said this was the cost of half of a night's stay).
6. On weekdays, they don't offer free safe drinking water in the lobby after 1 pm - you need to buy a bottle at the bar. They offer this all day from Friday to Sunday.
If you're fine with all that, there are still many benefits to this hostel:
1. This is a VERY cheap place to stay that is very central - close to the airport, and a quick Uber to most popular tourist spots.
2. We were happy to have good air conditioning in our room after hot days (would definitely recommend the Deluxe Room because of this).
3. The hotel itself is beautiful and well decorated.
4. The bed was very comfortable, and everything in our room worked well (shower, lights, air conditioning, all sockets).
5. I enjoyed the morning yoga, and while we didn't take any of the tours offered, it was nice to see there were a lot of options for guests.
6. I saw reviews earlier of the elevator being manned and/or not operational at times, but they seem to have resolved this issue and it was always working.
7. Despite the dodgy area, there is always security at the front door, making it feel safe once you enter the building.
8. The front desk staff were very friendly and accommodating, and all spoke English well.
9. Daily room cleaning was extremely thorough - it was nice to come back to such an immaculate room and clean towels.
