Mariana is an exceptional host. I stayed at her place for a month and she has been very helpful in answering and helping me in the daily life of living in a different country where I don't speak the language. The location is very convenient - a few minutes walk to the closest metro station, grocery stores and restaurants. The place is in the older part of town but it is well organized and tidy. She also reach out to me a few days before I arrive to ensure I know how to get to the place. I would highly recommend this place to anyone traveling to Lisbon.
