Last weekend or My weekend ("my last weekend" sounds more like it was the final weekend you spent somewhere in particular, rather than talking about how you spent the previous weekend- unless this is what you meant!)

Last weekend I went to Punta Umbría with my family.
I booked a room in a hotel. The rooms were very big, with two joined beds, a desk and a sofa. The bathroom was very large, but the shower wasn´t working properly, sometimes the water was too cold and 10 seconds later too hot.
The restaurant wasn´t big enough, therefore you had to wait in a queue if you wanted to come in before two o´clock.
There were two swimming pools, one for adults and another one for children. The water of the larger pool was warm.
If you wanted to go to the beach, you had to walk around 200 metres. The beach sand was full of little shell pieces. Bathing in the sea was prohibited by the waves, there was a red flag warning of the danger.
Near my hotel there was a little shopping centre. There were clothing stores, bars, restaurants, ice creams, etc. At night a lot of people enjoyed spending time in the bars and pubs with the live music.
I am awaiting my next free days to go out.


I hope this helps you a bit! You have good writing skills :)
