The room is great! Privacy was a wooden sliding door, but if you have a respectful neighbour, it will be all good! David is also great to talk to for tips around local food in the area. If you do get a chance to, ask him! You won't regret it! I had a very good last dinner in Barcelona thanks to his reccomendation ;) as well as breakfast. His cat is also a little playful one. Keep your bag straps at bay!
Also his house is super near the metro llacuna - less than 4 minutes walk? The neighbourhood may seem very quiet, but I assure you its pretty safe, as a solo female traveller walking back at 12 midnight.
