The apartment is nice and has got three good rooms with comfy beds. The kitchen is well equipped and the balcony is nice. There are two bathrooms, and we had some problems with both drains in the showers. The check-in went smoothly and the communication was good.
We only saw and experienced Lisbon by foot, and the apartment is located in walking distance to stores, groceries and the train station (all accessable within a 15-45 minute walk).
Would recommend.
