Overall the experience was good. Location is great: just a block away from one of the best breakfast places in the city (Maque). We used the rooftop for a small gathering and it was comfortable. We cooked for Christmas dinner and all appliances worked and dinner table and sofa were comfortable. The small garden is quaint and nice to look at. Also wifi was fast and we had a good time watching Netflix, etc.
There were some minor issues that when combined made this just an OK experience:
--Hot water: as others mentioned the shower has some issues where hot water doesn't last for too long. After we encountered issues they made some adjustments and definitely improved, but it was still not perfect.
--Noise: there was a construction site next door, but noise from there wasn't noticeable. Most of the noise came from other loud airbnb renters in a higher floor. Asked host to talk to them, but didn't get a reply. I did go upstairs at 1 am to ask them to lower it and they got better, but this group would often be drunk and shouting when leaving the building. Also, people from a few of the other apts would slam the metal door that is right out of the apartment making considerable noise at all times of day and night.
--Cold: we were there in winter and apt was a bit cold since it doesn't get much sunlight. They provide two heaters. A big one which works OK enough for the living room if you are watching a movie and a smaller one that is meant to be for the room, but is very noisy. If we brought the larger heater to the room the rest of the house would be cold in the morning. This "large" heater is quite cheap, so I think it would be an easy fix for them to buy an additional one.
None of this issues were huge: shower was manageable, noise wasn't unbearable, and it wasn't freezing, but we did experience some issues in these areas.
