In short: I don't think Uriel offers his room for rent very often, so I'd definitely suggest booking it if it pops up in your search. Our stay was perfect.
Uriel's house is very centrally located and has excellent connections almost everywhere, including a big Carrefour supermarket just a couple of minutes away. It appears that the whole house belongs to him, meaning you can access a range of very good (!) facilities, including a very big and well-equipped kitchen and two washing machine-dryer combinations. The room itself is spacious, has its own full bathroom (although there are two more you can use in the house), refrigerator, and microwave. The bed is king-size and has very high-end high tread-count sheets. There are very expensive toiletry items (e.g. a La Roche-Posay shower gel) for free use in the bathroom.
As a host, Uriel is exceptionally forthcoming and hospitable. We had a very late check-in, which he accommodated without any problem. He even offered us food (which was amazing!) and a drink after we arrived!
We would have loved to stay with him longer and would definitely stay with him again! 100% recommend!
