Patricia met us as arranged and whilst we have no Spanish she was able to give us all the information we needed and there's lots of maps and pamphlets to peruse. The apartment is very well located for a first visit to Barcelona, it's close to metro and buses and a number of important sights are within walking distance.
The apartment is a surprise, inside an historic facade is a very modern interior, well fitted out and with great light, especially in the morning, it wafts in gently starting the day.
There's a profusion of restaurants, bars, and cafes all around and markets, though the markets at Las Ramblas are another step up again.
We'd recommend visiting the Gothic area (around the Picasso museum) and also up to Montjuic perhaps to visit the Joan Miro Foundation. The Palau Güell is also worth a visit if you're taken by Gaudi's work.
Teo's apartment was great for two but could accommodate 2 couples also, as the bedrooms are at opposite ends of the space.
Finally we also enjoyed finding the Festa de Sant Medir on our doorstep the first morning, a tradition particular to Gracia in early March, how can one not enjoy having sweets thrown to you by people on horseback!
