Pros: Carla's place is exactly like in the photos. Bright, clean, and spacious. The kitchen has most of the items you would need for a short stay and light cooking. Neighbourhood is peaceful, walkable, 24h supermarket, etc. Carla is very responsive and was flexible with the check-in hours, which was greatly appreciated given my flight was delayed. Overall, highly recommended. Note: for those with luggage or limited mobility, there is no lift in the building, so you need to be comfortable with walking up two stories.
Cons: considering the property price, the shower needs to be urgently checked and maintained. The temperature is very hard to control (either boiling or freezing) and it seems the shower head is clogged, limiting the water to flow through the pores. I had to take a few cold showers, which was a shame.
Two minor recommendations: buying a spatula and a kettle (or similar) to the kitchen. Important utensils for cooking breakfast.
