The apartment is spacious, clean and beautiful. Just like the pictures. It was more than enough room for 4 ppl. Beds were adequate, showers were great, laundry was handy. No salt, spices, coffee, cooking oil etc. But kitchen equipment decently stocked. Small elevator available to take you up to the second floor, which is actually more like the fourth or fifth floor if you have trouble with stairs.
The location, although touristic, was very convenient. Easy walking distance to many places in the city. Adjacent to many metro lines. Felt very safe. About a half block east of Plaça Catalunya, where the airport Aerobus drops off (€5.90 each way).
For any place in Barcelona there is a mandatory tourist tax. You must pay it in cash, on arrival. It is €2.25 per person, per night.
One thing to be aware of for this place, although it is in the fine print of the listing, is that the host charges extra fees for many issues related to check-in. For example, if you check in on a Saturday or Sunday, or bank/stat holiday, you have to pay an extra €30. This is even if you check in during the assigned hours. Given that this is a fairly expensive place, and professionally managed (not someone’s home), we were disappointed by this. To avoid this fee, you also have the option of picking up the keys yourself off-site at a storage facility, approx 20 mins walk away in Eixample.
