Grinuy's apartment is a great base to explore Lisbon from. Its cosy and compact, and has the most comfortable bed I've slept in for years! It's not a big apartment but for may partner and I it was perfect as a place to rest after a long day of site seeing.
The location is great, its down a side road and on the 3rd floor so its quiet enough to not be disturbed by traffic or people in the street. Its also right on the famous tram 28 route!
