I was in the apartment with my 2 adult daughters and we felt right at home.
The apartment looked new and was very clean and luxurious and provided us with everything we needed. Everything was neat and organized and well equipped with all the kitchen utensils we needed. There was a shelf in the fridge for each of the rooms, and although there were 4 rooms, we hardly encountered the other tenants.
The location is right next to the Trinidad train station, there is a supermarket nearby, there is air conditioning (very important in summer and especially at night when closing the windows due to the transport noises outside).
Communication with Antonio was very pleasant, fast and efficient.
We walked everywhere, to Santa Catarina Street, the Riviera and also to Villa Novo de Gaia.
It is important for me to note that the issue of self-check-in did not match what is written in the apartment definition. I knew we would get to the apartment after midnight so this point was very important to me, and eventually we had to go after midnight to another address (about 10 minutes walk) to take the keys to the apartment and back to the address of the apartment itself.
I highly recommend the apartment
