Xavi's place is very spacious with a good size living room and nice kitchen. The bathroom has a tub in it and there is a shower in the tub.
The double bedroom is good size and the single room has space for hanging clothes.
We were given some milk, tea, wine, cookies and a few other things so that was nice in case we did not have time to go shopping.
The Central Market is only 400m or so away so very close and great place to get provisions.
There are lots of nice restaurants around and great places to visit.
You can take the 150 bus from the airport (€1.50 - pay on the bus) or the metro (€4.50). The bus takes about 50 min and is a 7 min walk to the flat and the Metro is 25 min but a 16 min walk to the flat. A taxi (using FreeNow app) is about €18-20 and takes 20 min (they can pick you up in front of the flat).
the flat also has a small balcony that just fits two chairs so you can sit outside and enjoy the sights over some drinks.
It can get a bit noisy at night but that is due to the great location. With the balcony double doors closed, it's is not too noisy. The view from the 4th floor is nice and there is a small lift for luggage.
The back bedroom (double room) is far enough away that it does not get much noise. The wifi was a tad slow in that room and it was a bit chilly in the mornings but electrical heaters were provided so it was no issue.
Communication was easy and quick using WhatsApp.
I would certainly stay here again!
Thank you Xavi and Olesya for making it a wonderful stay!
