The location of Anne's Air B&B is in a word - fabulous. It is within walking distance to anywhere worthwhile in Barcelona (Segrada, Ramblas, Market, Gothic quarter, harbor, zoo aquarium, parks and museums). The Appt. is large (3 bedrooms) specious and very nicely appointed for a very comfortable stay. It is also both quiet (excellent nights sleep0 and has several convenience stores and eateries/cafes across the street for essential shopping/breakfasts. Overall an excellent value contributing to a very enjoyable 4+ full days in Barcelona.
In addition, Anne's agent who handed us the appt., also provided us with a map and highlighted and explained some prime sites to visit and eat at sites, that all turned out to be "golden" recommendations of a knowledgeable local.
The only minor drawback is the late check-in (5 pm). For slights from the US, which arrive in Barcelona very early in the morning, if one wishes to sleep off the jetlag, we found it necessary to book the previous day so we can check in at 9 AM. This slightly lowered the otherwise excellent value of the B&B.
