Antonio is a fantastic host - easy to communicate with, and had some great suggestions for where to eat!
The flat was comfortable and cosy. We really felt at home! The kitchen is well equipped with everything you'll need to cook meals at home, but the flat is also a stone's throw away from a lot of good restaurants. That said, because it is so central, it can get a little loud in the evenings, but I still slept very well. Bring earplugs if you're a light sleeper and you should be fine!

As for the bathroom smell, this is typical of old buildings in Europe, and I've come across many during my travels. It's completely manageable with opening windows and using the exhaust fans. Antonio has also added some scent diffusers and candles that can help with that. Otherwise, the flat is very clean and nicely renovated. I'd stay there again in a heartbeat!
