Thinking it is too good to be true? DON'T!!! As all the previous reviews state, we had a great experience in one of Telmo's Airbnb properties.
The place we stayed in was as seen and described on Airbnb. Brand new, spacious, nicely decorated, very clean and extremely well located (a bridge or one subway station from the center of historic Porto).
Communication with Telmo was easy, quick and very useful. He is a kind host always willing to help if needed but at the same time he will respect your privacy (even though he lives in the same building).
We would recommended this host and his properties to anyone looking for a place to stay in Porto! Enjoy!!!
