I came to Lisbon for 4 nights with my mum and would have no hesitation in recommending Teresa’s apartment. The bedrooms were spacious and the apartment was really clean. The location of the apartment was great and only a 2 minute walk to a bus stop and a 15-20 minute walk to the main tourist sights. There was also a supermarket about 100m away, which was really handy for picking up essentials.
The only slight issue was that the street outside got a bit noisy at night as there is a restaurant opposite but only one of the bedrooms faced the street and so light sleepers could stay in the bedrooms at the back of the apartment.
Teresa was a great host and was extremely punctual at replying to messages and personally welcomed my mum and I when we arrived.
