We had a lovely stay at Luis and Elisa's apartment in Porto. The location is central and it is easy to walk to almost all the sights you would want to visit. The free included breakfast and welcome bottle of wine were also special treats that made us feel very welcome. If you sleep with the windows open, the square below can be quite loud (especially on a festival night like when we stayed!!); however, we did not find this to be a problem when sleeping. Luis also provided us with earplugs in case we needed them. We would highly recommend this apartment for anyone going to Porto.
