It was fairly easy to get to by bus and Metro. But I only had one small bag, I wouldn't recommend doing this with big luggage. It cost 5 euro for the bus to the train station/metro station then 1.20 euro for the Metro. It's a 2-3 minute walk from the station.
The guy downstairs of the building is rude, but managed to get him to tell me where to go. This place is on the 4th floor and it's confusing because there is another Bovio suited on the 2nd floor.
The older housekeeper lady is just incredibly lovely and sweet, she let me dropp off my bag to store until check in. She doesn't speak much English but she's just a legend, badass I loved her!
Stayed here for one night with my friend, requested 2 beds got two beds but one was a baby twin bed and the other a full/queen. The rooms are outdated, beds are springy and hard. The room had a cool big old window it had Air-conditioning. It was clean but I found hairs on the shower wall, a towel hook was barley hanging on and things just seemed used and abused. The keys were oldschool skeleton keys. There is an elevator. Good enough for one night and if you're not too picky.
Overall it's in a great location, walking distance from the Spanish quarter. There's plenty of cafe's to grab something to eat and drink around.
