We didn't meet Luis himself but the communication went very well and the checkin worked professional and well. Our room was nice & big, the bed comfortable and the kitchen very well equipped for our needs, the bathroom was a little bit older but clean. For the city center with some of the main sights you have to walk for 20 minutes or take the nearby metro, but that's known in advance.
The only real downside left to mention - and that's in no way to our hosts fault - is that the other guest did make a lot of noise at 3 in the morning and you might wanna bring earplugs to
avoid the thin walls
