We had a really great time at Teresa's! The place is the same as it looks in the pics: perfectly clean, lighty, well-decorated and spacious.
The bed + bedclothes and the sofa are amazing, very comfortable! Furthermore, everything smells good and Teresa provides all you could need in a home. The apartment is well-located (Baixa Chiado is 10-minute walking or less), near public transportation and even so very silent.
The owner is extremely kind and helpful - she gives lots of information about Lisbon and near cities, provides lots of maps, travel books, guides and things like these. You can ask her everything you want to know about the city and you'll receive precious information and be very well treated.
I have nothing to complain about our stay here and I highly recommend this place!
