I would like to thank Thac for everything because I've never travelled alone and never been in the US before. He helped me to figure where was my university, he went with me to buy groceries at organic food markets, and to buy a SIM card as well. He printed two copies of a document that I needed and was always helpful. We dinner with a friend of his in the first night and I cooked a Portuguese meal, we chat and it was a pleasant evening.
Everything is organised, clean and the bed is comfortable. The wifi works very good and I could use the kitchen everytime I needed.
I couldn't ask for a better place to stay, i would definitely come back. I would like to add that you're always invited to come to Portugal. See you soon and thanks a lot once again!
