Starting from the beginning:
1. Communication with the host is quick and pleasant. Thierry answers questions and doubts comprehensively and with humor. He is committed and willing to help.
2. The contract you sign at the beginning does not exactly match the offer, but rather the flat rental in general. In my opinion, it would be good to improve.
3. The apartment is situated on a hill. You have to keep this in mind when you want to get there by car. Wherever you want to go, it involves walking up and down.
4. The apartment is air-conditioned and well protected against the sun. Unfortunately, there is moisture there, you can feel it in the air in the rooms (it is better when the windows are always open), but also in the cabinets, especially in the kitchen and bathroom. My hairbrush that was in the drawer still smells like a basement. I do not recommend a longer stay for allergy sufferers.
5. The apartment is spacious and nicely furnished. There is no shortage of hot water. There is a cooker, an oven, a microwave, a toaster and a capsule coffee maker (I recommend buying capsules). I found all the dishes and pots I needed. You can use dishwashing liquid, frying oil, tea, sugar.
6. Internet in the apartment receives well mainly in the living room and is stable. There are breaks at work, but only on weekends. The router is behind the wall in the host's apartment.
7. The apartment is located in a quiet area. Sounds from the bar or the disco do not disturb. However, you can clearly hear passing cars, especially motorbikes. They also often drive at night.
8. Cleanliness in the area. The city of Barcelona is very concerned about cleanliness. A street water sprayer runs along the street and washes the pavement and bins under pressure. It is salutary because many owners in the area do not clean up after their dogs.
9. You can park your car on a hill near the park and in the nearby area on a free public car park.
10. I would like to add that Barcelona is a really big city. It can take you an hour to walk to the subway and then to go by subway to the beach.
