Liliana is really kind, she called me on the day of the arrival to provide information on the best way to reach the apartment.
She speaks a really good english - and a very good italian too!

The beds' size is halfway between a single and a full double bed, so this has to be considered in larger groups of travellers.
The streets around the apartment might be quite noisy at night, given the position of the house. If the weather's hot and you need to keep the windows open, you will likely hear a bit of noise.

The house was very, very clean, and it offers pretty much everything you will need. The two bathrooms are small, but the two showers can operate at the same time without any lack of hot water, and this is really comfortable.
Lastly, it's position is great: it's really close to praça da Figueira, Rossio and praça do Comércio, so it is in the very center of la Baixa.
