In general the accommodation was good. We really liked the way how the self check in was organized and that the doors are locked by key-card. All descriptions Maria gave to us were good. In addition the house itself is beautiful and very stylishly furnished.
There were just a few things we didn't like that much. If you decide to stay here be aware that you share the house with many other people who may come home late at night, taking showers by night, talking very loudly and being very noisy in general.
Also the beds weren't that comfortable and we were afraid that they could break down in the next moment.
In addition we were a bit unlucky because the electricity in the house shut down three times in seven days so the sockets were out of power and we couldn't charge our phones. But Maria always did her best to solve the issue quickly.
Even if we haven't met Maria personally we really enjoyed our stay in Porto :)
