My family and I (2 adults, 2 teenagers) spent a week at Ana's apartment and it was a great base for us. The apartment itself was lovely, fresh and clean with traditional looking tiles on the floor. It had plenty of space for the 4 of us to spread out and have our own space after a busy day. I found the double bed comfortable but my daughter didn't find her single bed comfy, this is just down to personal preference, not a criticism of the host. There was plenty of wardrobe and drawer space for unpacking. The bathroom was a great size. It had the only mirror in the apartment so another would have helped us when the bathroom was occupied. The balcony was nice, overlooking other buildings and the hill of Montjuic. However, we found it hard to fit 4 chairs out there, it's long but not deep. It wasn't a huge issue for us but something to note and obviously something the host can't change. The kitchen was small but we had enough space to prepare breakfast and lunch. There were plenty of utensils. We didn't cook dinners though and I did see a note saying the cooker only worked at a low temperature. I didn't investigate that more.
In terms of location we thought it was great! The metro was only 3 minutes walk away, the bus only a little more than that. There was a Lidl only 1 minute away which we used very often. There were cash machines nearby. The one on the way to Lidl doesn't charge for transactions. It was only a 10 minute or so walk to La Rambla. It was a 20 minute journey by bus to the beach. There were nice little bar/restaurants on the street and it felt like a nice place to walk home to.
Ana allowed us to check in a bit earlier and the cleaning lady met us with the key. She was very patient while we went to get the Tourist tax cash. Ana was very quick at responding to my messages throughout the trip. She couldn't have been more helpful. Naturally, on any trip there a little things that occur and Ana took care of them straight away and it seemed no hassle at all. Checking out was easy too. My daughter left a few items in her drawer and Ana has gone the extra mile and sent them back to me.
Overall a great place to stay!
