Rodrigo seems like a good guy, very friendly and willing to help (to a slight exess, but that's subjective) and the communication is easy.
The check-in was rather awkward though, as we couldn't have the entire place to ourselves since Rodrigo was still there after the check in. We were really susprised to find him in the apartment after we did some exploring (around 5 hours after the check in..)
The place is very (very) small, but if you're there only overnight or just need a bed to sleep in, I guess it does the trick. Mind though, if you're taller than 5'8" you're probably gonna have difficulties standing up in the bathroom.
The location's great, easy walk (albeit lots of climbing of the stairs, of course) to Alfama, simple commute to the other districts of the city.
Thanks!
