We stayed here for almost a month and the location is great. It's technically in Doctores but it is literally right across the street from La Roma (it's basically La Roma). There are two parks right next to the apt and it's so peaceful.
-The building is brand new, super secure (guards outside) and very clean. It's a really nice place!
-WiFi is not bad, we didn't have that much trouble but there was a slight lag occasionally. Not a huge deal.
-If it is hot outside, it will be hot inside. There is not any ventilation so it would feel very warm during peak day and opening the patio door doesn't help as the air outside is warm too. But when the weather is nice, it is really great and nice to open the patio door.
-It's really close to lots of restaurants, bars, grocery stores, etc.
-We re-washed the bed linens because they didn't look clean.
-Kitchen supplies could be better. The pans were very old and stained (need to be replaced) and the coffee maker was very dirty on the inside. I bought a new pan to make food. Maybe this will change soon though.
-The concierge Juanito is so kind and helpful. Really enjoyed talking to him!
All in all, it's a nice place to stay if you are one person. Long-term, it's not very comfortable. However, take this with a grain of salt as the owners could improve everything by the time you're reading this and looking to book!
