My stay at Miriam's was good. The area of the building is safe. I was a single woman traveling and felt very safe. Also, the apartment is immaculately clean and is exactly as shown in the photos on the airbnb.com website.
Miriam and her husband greeted me with the keys on time. The communication went very well. They also provided me with easy directions to the apartment. It helped that I mapped out the building on prior to arriving so that I knew how the building and the surrounding streets looked. The building is only a 3 minute walk from tbe Trinidade metro station.
The buiilding is also within a 20 min or less walk from EVERYTHING.
The only watchout I have is that because the building is so close to everything, the noise level is nonstop from 7am - 3am in the morning. You will hear passerbys talking loudly, mopeds, cars and trucks. So if you are a light sleeper, please keep that in mind. However this might be the case with most of the apartments that are centrally located.
