Carlos and Cristina's apartment is superbly located just off the Douro River. It has three big windows that open to a stunning view of the lower city and a "to the side view" of the Douro. It was clean and comfortable. We arrived in the midst of a heatwave that made the loft a bit warm for sleep (even with the air conditioning), but my twenty something year old daughters assured me that the convertable sofa provided a more than acceptable aternative. Speaking of air conditioning, it worked great. The lower living areas of the apartment were cool even with the brutal heat (not my words, but the words of residents we spoke to). Some of the other reviews mentioned mentioned a lack of water pressure. That was not an issue for us and was only noticed in the shower, but was no big deal! The stairs are steep and long. It is definitely not for people with mobility issues or those with a lot of luggage. There were also comments about not being able to place toilet paper in the toilet after use. That is true. We did not see that in the description and there was a difference in the rules emailed to us before arrival and the rules written in the apartment (which say only toilet paper can be placed in the toilet). We clarified with Carlos and Cristina that no paper of any type may be placed in the toilet and, instead, must be collected in the trash. That's a small factor in an otherwise great place to stay! Carlos and Cristina communicated quickly to any questions we had. They were nice enough to allow their apartment to be used to store our bags for an hour because of our slightly early arrival. All in all a beautiful apartment in a beautiful city with hosts that are professional and responsive. A great experience!
