We enjoyed our stay in Lissabon and especially at Christina's apt. very much. It was very very clean and we had everything we needed. Besides that, the set up with the furniture is very cosy. We felt comfortable as soon as we walked in.
The area, the apt. is located, is perfect to get around very easily. Nothing is very far away: right around the corner you find nice cafés, restaurants as well as little stores to buy groceries. We enjoyed our breakfast several times at the park (about 8 mts to walk) named "Jardim do Principe Real".
At any time, Christina answered any question and was very helpful.
We would definitely stay again at her apt and recommend it to everyone.
