Montserrat was an amazing host! She was very helpful and sweet. Her breakfast was very nice, she also offers tea and coffee! Her place was a 30 minute bus ride to the beach and 20-25 minutes to the city centre by bus (metro is quicker). It is very close to the main train station Diagonal.
There is a lift in the building (only 5 stairs up from the entrance, not suitable for wheelchairs). I would recommend her place.
The room fits two people and is fine for sleeping, very comfortable beds. But not much space to open any suitcases etc. however she offers wardrobe space to put your clothes in which works well.
It is also a 2 minute walk to the nearest supermarket, which has most things you may need to cook.
