Prima and her sister were lovely and very friendly, and always asking if we needed something. The apartment is very small but cozy and well decorated, located in a quiet area really close to Bairro Alto. We really enjoyed our stay there and would recommend it.
Just one piece of warning: if you happen to have a flight at the evening (as we did) be careful because we couldn't leave our luggage in the appt !!
The public storage was full, so our last day in Lisbon was mainly an odyssey strolling around those hills with the bags!!!
