The first question to be answered - would we stay here again - the answer is yes. Tono is a very solicitous and responsive host. He could not meet us upon his arrival and his arranged for his daughter Jana to met us. She was very generous with her time and showed us the various aspects of the apartment and answered our questions. Throughout our stay, Tono stayed in touch and answered via email our questions.
The apartment though small by American standards, but was sufficient for our needs. It is clean, well laid out and the furniture and appointments are new. The bed is comfortable. The living area could use a higher level of lighting for reading at night. The bathroom is fully tiled and the stand up shower is quit nice.
The Poblenou area is away from the city center, but the metro makes traveling very convenient. There are many small shops and a nice city market minutes away, as is the beach. If you want a place near the beach this is the area. This also appears to be an area on the edge of gentrification development. There are a number of nice restaurants close by.
The negatives are: this is a 3 story walk up(2rd floor) and on a street with bus and traffic. There are times during the day when the street noise may preclude opening the terrace doors.
Again a very nice apartment and a good location & close to the beach.
