The situation of the place is very convenient, about 10 minutes walk from Sol if you walk at a reasonable pace, and very close to a couple of subway stops if you want to move farther afield. As expected there are plenty places to eat nearby, but there are also a number of small supermarkets. In addition, there are a couple of takeaway coffee shops nearby, for those who are used to the barrista-style coffee you get in UK/USA/Aus/NZ. The opening times of these places are a bit wacky, however.
The amenities were as expected; WiFi and A/C worked very well. We did not use the hob provided in the kitchenette area, but the toaster and microwave worked well. The cleanliness was great too - the place had clearly gone through a good clean prior to our arrival.
One (minor) issue is that the mattress was not great. It sagged in the middle, which might pose an issue for those with back issues. It is also worth noting that the walls are quite thin so bring ear plugs if you are a particularly light sleeper.
Lastly, Carlos was a great host. Very communicative and helpful! Check-in/out instructions were very thorough and made the whole process very smooth.
Cheers, Carlos!
