We are a mature couple traveling with a relative and we stayed for 3 nights.
Raúl's apartment is in a good location, spacious and stylish, it has an adjustable bed, which as expected was very comfortable, but to our surprise, the sofa bed was very comfortable too.
Something we didn't noticed in the pictures is that the apartment also has a skylight at the back, which helps a lot providing natural light, even though ventilation appears to be limited to the front door and small window, the apartment wasn't stuffy at all, and we didn't find any signs of moisture.
WiFi Internet was the fastest we had during our travel in Europe.
Unfortunately as described, the apartment has no stove, but it has a microwave that can be handy.
There is also a coffee machine with a good supply of capsules, kettle, toaster, etc.
the only thing we didn't like as much is that it has no hot water in the kitchen sink.
We recommend this place and would certainly stay there again.
