Antonio's place is very centrally located so it was very easy for us to walk to local attractions in Madrid. It is also a clean and comfortable place to sleep - the bed was very nice. Antonio was also very helpful with check-in and check-out. There were only a couple things I could fault the flat for:
1. It was smaller than expected as it looks much bigger in photos. However this didn't matter too much to us as it is very cute and well furnished.
2. But, it didn't feel super welcoming - there were no suggestions on local restaurants or places to check out, something I am very used to when staying in Airbnbs. There mostly were strict intsructions on how not to damage the flat (understandable), but it just felt a bit cold.
3. There was also a camera on the outside of the flat (not on the inside, just outside the door into the flat itself). I understand that security is important, but this made us feel a bit on edge/watched.
