Elis' place is absolutely wonderful and staying here will definitely make your visit to Porto even better. The appartement is very clean and everything you might need is thought of. The walk from the appartment to the center of Porto is only 10-15mins, and there is great access to busses and the metro. Elis herself is without a doubt one of the sweetest persons we've ever met and the best host. She will make you feel as comfortable as possible and has some great recommendations for restaurants and things to see/do in and around Porto, of all kinds. And then there is the breakfasts: there is so much to choose from that there hardly is space for your plate on the table, and it's delicious.
We will definitely recommend Elis' place to everyone and if we are in Porto again some day we for sure will go back to Elis!
