We were welcomed in person and the host was really forthcoming. We really felt well taken care of and the place was perfect for us. Everything one would need and in style, too ;-). The studio is super central, right at the Dom Luís I Bridge, the old part of town which is likely to be the area one wishes to explore as a tourist.
The only downside I can report is that you can hear clearly the tram when crossing the metal bridge, but it doesn't run during the night, so really not an issue at all.
Highly recommended place and host!!!
