We found Arne and Iker to be very responsive when problems arose. The apartment is a nice size and well furnished and well stocked with kitchen accessories. We selected this unit due to elevator, parking, washer, dryer and balcony. We were warned that there was scaffolding which would "affect the view at its smallest proportion". We found that the view was totally obstructed and that there was no access to balcony and washer which was located on balcony.
The location is not the greatest. It is relatively close to Parc Guell, but walking to PG involves mostly uphill. It is on a very busy street and not very amenable for walking. In short, it is not the best if you are looking for "walkability". We did not find any good restaurants nearby, but there was a grocery store downstairs. The metro station is nearby. Taxis were hit and miss, so be sure to call for taxi if you need one.
VERY strong smelling pine scented cleanser was used to clean prior to our arrival and the whole unit and even the towels smelled strongly like the cleanser. We tried opening up windows as much as possible to air out, but were concerned about construction dust.
On our last night, the electricity went out in the apartment (rest of building had power). Our host responded quickly and remedied the situation, and told us "to do not plug all things at the same time." There had been four of us there for 4 nights with no power problem, and only two of us for the last two nights and the two of us were not even there when power went out so could not have been using much power.
Although this could have been a solid 4 star property with one star removed for location, what we experienced was only worthy of 3 stars.
