Fantastic B&B with even better hosts, Ana and Victor. Very friendly and go out of their way to answer your questions and accommodate your requests. The metro stop, Diagonal, is a hike but not bad. From Airport, it is better to take the 2 metro lines (F9 and then F5) than take a taxi or Uber. This is the most economical way as well as the quickest way to get to the B&B. After that, for local transport the Bus V13 is just across the road and pretty much gives you access to all other modes of public transport. Even though the B&B is on the main Avenue called Diagonal, it is still quiet with the thick window panes. In the evenings, you can open the bedroom balcony (a small one but two can sit and watch the vehicles and people go by) and relax or read a book.
A nice touch and boon for early morning raisers like me--Ana leaves instant Nescafe coffee and milk at the counter and there is a plug-in hot water kettle. You can help yourself to some hot coffee if you are an early raiser.
The breakfast is very nice albeit a little late start of 8:30 AM. I wish they would start at 7:30 or 8:00 AM. The little courtyard outside the breakfast room is very nice and you can sit there and take pictures. The breakfast contains cereal, hot milk, fruits, cakes, eggs if you want Ana to get it for you, etc. More than enough to get your day going.
The room and bathroom are very nice. The shower is awesome. No complaints at all. Wifi also works beautifully. No TV in the room.
