TL;DR: great location, spacious and luminous apartment, nice views from the living room; check the internet connection with Charles - there are options; could be a bit noisy in the summer when you want your windows open - it’s located on a corner of a very busy street (Corts Catalanes).
Long review:
The apartment is located in the ‘right’ part of Eixample, on the 5/6th (I’m still not sure) floor. There are two subway stations nearby (one is around the corner, another one is 4 min away). The neighbourhood is rich with food stores, cafes, etc. The location is very strategic if you like to walk - you can (and probably will) walk anywhere.The most famous Gaudi’s buildings are around 10 min walk, the beach is some 25 mins away (or a couple of stops by subway).
Views are spectacular. The elevator is ancient but in full working order. Every room has a private balcony, some are just alcoves, some are quite large - you can chill with a glass of wine and a plate of jamon/cheese.
The apartment is huge. In fact, photos don’t do it justice - it’s much larger than you can tell from the pictures provided. Maybe Charles should ask a (better) photographer to take pictures using a wider (an ‘ultra-ultra-wide’) lens. All four bedrooms are great, all beds are very good. There is ample space for your luggage and things. The kitchen is lacking a proper espresso machine (the ‘american style’ dripper is atrocious), but everything else is in place and in full working order - a stove, a kettle, even a toaster. There’s enough tableware for 10 persons, I think - dishes, glasses, mugs, everything.
The heating is fully working (which is never a certainty in Europe!). The floors are covered with tiles so bring your warmest footwear if traveling during the winter.
The default internet connection is rather slow, but we asked Charles and he supplied us with an alternative SSID/password, which was working really great. There is a TV in the living room, with ample HDMI/USB connections, we had no problem connecting our Chromecast for youtube/netflix/etc. There is sufficient number of power outlets in every room.
The lighting is uneven (different bulbs, different light intensity in different rooms/areas) but we never had real problems with it, it’s just a bit distracting.
All in all we had a great time, enjoyed our stay with Charles immensley.
