I was in town for a week for an engineering conference and stayed at Miguel and Eloi's flat. Miguel met me when I arrived and took some time to point out on a map all the best food and sights in town. The recommendations were fantastic! The flat was pretty much as advertised, down to the beautiful view of the Igreja do Carmo across the street. The bed was comfy, the wi-fi worked well, the location top-notch for exploring town, and the decor was modern and inviting.
It should be noted that I had to keep the windows open for ventilation, and - being next to an open plaza - the students came out partying from 23:30 to 3:30 or so. I quite enjoyed the din of music and people talking, but I could see how others might not share my sentiment.
I would say the studio was perfect for my purposes - a single student attending a conference and doing some sight-seeing on the side. Thanks Miguel and Eloi!
