I stayed a week in Martha’s lovely 5th floor large modern apartment. She met me at the door as it is not easily identified but is the first double door next to Haworth Office Furniture. An old fashioned elevator takes you to 5th floor and reminds me of older New York apartments. My room was nice with a large bed, good sized bathroom and a laundry room. The kitchen is modern and well-equipped. The location is great, there is a taxi stand in the same corner. I was able to walk to Boquerias Market and Las Ramblas and all the way to harbor but buses, metro and taxis are all very close. I took day trips on Renfe train to Girona and Figueres, easy from Barcelona Saints station.
Martha is an outstanding hostess, kind, helpful, generous. She even arranged my taxi to airport at 3:30 am although she was away on a trip. She gave me excellent ideas for sightseeing. She is definitely a 5 Star Superhost. I recommend you stay with Martha if you are lucky enough to visit Barcelona.
