Oleksandra was very accommodating with regards to our early flight by letting us drop our bags off in the morning so that we did not have to carry them around all day until our 5pm check in. She offered us a lot of advice on arrival and a big glass of water which went down a treat with the heat.
Oleksandra's apartment was in a terrific location. 5 minutes walking distance from the metro (green L3 line) and buses which take you anywhere you need to go in a matter of minutes. They also link up to other train services in the city if you would like to go for a day trip to one of the towns nearby. The apartment is close to many of Barcelona's main attractions by walking and there is supermarkets, restaurants etc nearby as well which you can walk to in 5 minutes.
All amenities necessary for a comfortable stay were provided, however, full apartment air conditioning was not on all the time (sometimes when everyone was home). We were provided with a small fan but it was still very hot and humid. But this is to be expected when you travel in the middle of summer.
Oleksandra is a very friendly and approachable host and I would highly recommend her apartment for anyone visiting Nice.
